Error: internal error: getTypeDescAux(tyExpr) when getting the type of an element of varargs[expr]

[ReneSac]

When using simple expr it manages to get the type right as int.

import typetraits

proc foo(a:varargs[expr]) =
  echo a[0].type.name

foo(1)

Results in:

Error: internal error: getTypeDescAux(tyExpr)
