(cherry picked from commit 8bfc396a4d)
Add a macro `enumLen` which is used to determine the number of items in
an enumeration type to the `typetraits.nim` module. Also, add unit tests
for it in the `ttypetraits.nim` module.
Related to nimlang/Nim#15824
* typetraits: add support for nnkTypeOfExpr
* typetraits: don't wrap typedesc symbols in StaticParam
* typetraits: add nested generics support to genericParams
* typetraits: make genericParams understand array[I, T] whackiness
Also moved tests to ttypetraits
* typetraits: clarify comment on genericParams
* 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.
* rename 'lenTuple' to 'tupleLen'
Rationale:
`lenTuple` is a tuple consisting of lengths (e.g. `(1, 5, 0)`),
`tupleLen` is a length of a tuple (e.g. `tupleLen((1, 5, 0) == 3`)
* rename 'lenVarargs' to 'varargsLen'
The same rationale as a previous commit. Consistency.
* fix deprecation; fix indentation
* git clone: use -q
* fix Warning: pragma before generic parameter list is deprecated; fix typo
* bugfix: sysTypeFromName("float64") was never cached
* remove disabled (and obsolete) ttypetraits; rename ttypetraits2 => ttypetraits
* D20200105T085828 fix super strange bug that causes CI to fail: builds.sr.ht with: `Error: Settle timed out after 120 attempts`
* add `isNamedTuple`; make $(1, 2) be (1, 2) instead of leaking implementation detail (Field0: 1, Field1: 2)
fixes this: #8670 (comment) /cc @alehander42 @Vindaar @mratsim
* Note: isNamedTuple is useful in other places, eg #10010 (comment)
* move isNamedTuple to helpers.nim to avoid exposing new symbol to system.nim
* remove workaround in tests/vm/tissues.nim failing test now that #10218 was makes it work
