metagn 0e2b34ce35 fix subscript magic giving unresolved generic param type (#23988) 
fixes #19737

As in the diff, `semResolvedCall` sets the return type of a call to a
proc to the type of the call. But in the case of the [subscript
magic](https://nim-lang.org/docs/system.html#%5B%5D%2CT%2CI), this type
is the first generic param which is also supposed to be the type of the
first argument, but this is invalid, the correct type is the element
type eventually given by `semSubscript`. Some lines above also [prevent
the subscript magics from instantiating their
params](dda638c1ba/compiler/semcall.nim (L699))
so this type ends up being an unresolved generic param.

Since the type of the node is not `nil`, `prepareOperand` doesn't try to
type it again, and this unresolved generic param type ends up being the
final type of the node. To prevent this, we just never set the type of
the node if we encountered a subscript magic.

Maybe we could also rename the generic parameters of the subscript
magics to stuff like `DummyT`, `DummyI` if we want this to be easier to
debug in the future.

Nim Compiler

  • This directory contains the Nim compiler written in Nim.
  • Note that this code has been translated from a bootstrapping version written in Pascal.
  • So the code is not a poster child of good Nim code.

See Internals of the Nim Compiler for more information.
