* fixes overloading resolution for passing owned(Future[string]) to Future[T]
* WIP: make --newruntime work with .async
* memtracker: make it compile again
* make Nimble compile again
(cherry picked from commit 5f515410af)
* mark user defined destructors with sfOverriden to simplify the logic
* refactoring in preparation to merge liftings and generic instantiations for destructors
* ast: introduce nkHiddenTryStmt for destructor generation in order to be able to optimize better the code later on
* renamed 'patterns' switch to 'trmacros' as it was totally misleading before
* destructors: introduce tfCheckedForDestructor flag in preparation of strict =destroy checking
* test for invalid/too late destructor introductions
* liftdestructors: make code robust for nimsuggest
* --newruntime works for hello world again
* newruntime: code generation for closures
* kochdocs.nim: code cleanup
* docgen: nicer indentation
* parser.nim: code cleanup
* fixes#10458
* make tests green again
* make =destroy mixins
* gc:destructors: produced C code is almost working
* --gc:destructors simple program compiles (but leaks memory)
* gc:destructors make examples compile in C++ mode
* destructors: string implementation bugfixes
* strs.nim: minor code cleanup
* destructors: builtin seqs are beginning to work
* remove debugging helpers
* compiler/sem*: better lineinfo for templates
Lineinfo for templates is inconsistant across the compiler, for example:
doAssert true
^ ^
a[int](10)
^^ ^
The `^` marks where the compiler thinks the template starts.
For qualified call, we got the same situation with `proc`s before #10427:
system.once
^
Generics lineinfo within template declaration is also incorrect, for
example, this is where the compiler believes the `T` in `[T]` is:
template a[T](b: T)
^
This PR addresses all of these problems.
* nimsuggest: add tests for template highlighting
* fix#10339 by checking for nkObjConstr
* revert check for nkObjConstr, return type from nkEmpty node
The correct type needed in `semObjConstr` to fix#10339 is indeed
available, but attached to an `nkEmpty` node. These were previously
discarded in `semTypeNode`, which is used to extract the type for the
object.
* simplify return of PType from `nkEmpty`
* also fixes#9866, add test case
