Injected symbol is not visible in generic procedure

[haxscramper]

Identifier identifier in template is visible in regular code, but fails compilation with undeclared identifier error when used in generic procedure.

Example

template getSome(val: typed, injected: untyped): untyped =
  let injected = val

block:
  123.getSome(resVal)
  assert resVal == 123
  discard resVal
  
proc g[T](arg: T) =
  arg.getSome(resVal)
  assert resVal == arg # works fine!
  discard resVal # fails to compile

g(12)

Current Output

/usercode/in.nim(14, 11) Error: undeclared identifier: 'resVal'

Expected Output

No compilation errors

can you minimize to something that doesn't have any imports?
also {.inject.} doesnt' seem needed since injected is a template argument, IIRC

might be a duplicate but I don't remember which issue
