This is in reference to a [feature
request](https://github.com/nim-lang/Nim/issues/22142) that I posted.
I'm making this PR to demonstrate the suggested change and expect that
this should be scrutinized

fixes#23200, fixes#18866
not turned to `tyUntyped`. This had the side effect that anything
previously bound to `tyAnything` in the proc type match was then bound
to the proc return type, which is wrong since we don't know the proc
return type even if we know the expected parameter types (`tyUntyped`
also [does not care about its previous bindings in
`typeRel`](ab4278d217/compiler/sigmatch.nim (L1059-L1061))
maybe for this reason).
Now we mark `tyAnything` return types for routines as `tfRetType` [as
done for other meta return
types](18b5fb256d/compiler/semtypes.nim (L1451)),
and ignore bindings to `tyAnything` + `tfRetType` types in `semtypinst`.
On top of this, we reset the type relation in `paramTypesMatch` only
after creating the instantiation (instead of trusting
`isInferred`/`isInferredConvertible` before creating the instantiation),
using the same mechanism that `isBothMetaConvertible` uses.
This fixes the issues as well as making the disabled t15386_2 test
introduced in #21065 work. As seen in the changes for the other tests,
the error messages give an obscure `proc (a: GenericParam): auto` now,
but it does give the correct error that the overload doesn't match
instead of matching the overload pre-emptively and expecting a specific
return type.
tsugar had to be changed due to #16906, which is the problem where
`void` is not inferred in the case where `result` was never touched.

* Add testcase
This tries to use a concept with a doc comment which currently leads to a segfault
* Ignore nil nodes which happen when there are doc comments in new style concept
This was done instead of semming the comments since `semConceptDecl` says it only supports lists of actual statements
* Go with alternative fix: Sem comments but ignore them
Since `nil` could mean anything it is best to not silently ignore it (In case another nil problem happens in future
Also fix test case so it isn't an infinite loop
* better error messages for dot operators [backport]
fixes#13063
* also fixes#7777
* fix#6981 and #9831 too
* fix
* minor improvement
* sus test fixes
* make test multiplatform lol
* fix nimsuggest test, extra improvements
* deprecate unsafeAddr; extend addr
addr is now available for all addressable locations, unsafeAddr is deprecated and become an alias for addr
* follow @Vindaar's advice
* change the signature of addr
* unsafeAddr => addr (stdlib)
* Update changelog.md
* unsafeAddr => addr (tests)
* Revert "unsafeAddr => addr (stdlib)"
This reverts commit ab83c99c50.
* doc changes; thanks to @konsumlamm

* fixes#15210 [backport:1.2]
* make tests green
* make ordinal work
* makes Swapable test compile
* make Indexable example work
* concepts: 'self' is now 'Self'
* concepts: make Dictionary example compile
* document the new concept implementation
* concepts: make typeDesc work properly
* concepts: allow documentation comments (d'oh)
* Error -> Defect for defects
The distinction between Error and Defect is subjective,
context-dependent and somewhat arbitrary, so when looking at an
exception, it's hard to guess what it is - this happens often when
looking at a `raises` list _without_ opening the corresponding
definition and digging through layers of inheritance.
With the help of a little consistency in naming, it's at least possible
to start disentangling the two error types and the standard lib can set
a good example here.
* fix#13538 sigmatch now sorted and has reliable order
* re-enable tests that were disabled because of that bug
* fix remaining tests and un-disable 2 other tests that were affected by this bug
* ungenericise unsigned ops, remove nimNewShiftOps
* fix/remove tests
* update t6448
* fix line info
* disable on 32bit
* fix different line info
* add changelog entry
