bug.d(2): Error: undefined identifier lo, did you mean variable lo2?

Both templates are match with conversion.
During ordering the first template is instantiated
with foo!(0, lo) and semantic is run in the wrong scope.
It seems that we need to create a scope and run semantic
while creating the dummy args.

There was a typo in the previous code example.
