An auto return type specified in a macro definition causes an internal error of the compiler. The commit bf592c4 introduced the bug.

Example

import macros
macro m:auto = newStmtList()

Current Output

t.nim(2, 16) Error: internal error: assignment requested for type: untyped
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c <file>

I noticed because it affects https://github.com/andreaferretti/react.nim (it can be fixed with minor changes, but it is probably worth fixing in the compiler instead)
