Comment(by reinerp):
Ok, I agree that
{{{
InfixE Nothing plus (UInfixE 1 plus 2) -----> (+ (1 + 2))
}}}
is the right thing to do. But we need a representation for {{{(+ 1 +
2)}}}. I think we should use
{{{
data Exp =
...
UInfixE (Maybe Exp) Exp (Maybe
Exp)
...
}}}
Using {{{InfixE}}} just doesn't work.
