Say I'v got some code like this
match exp with
| Addition(lhs,rhs,_) -> Addition(fix lhs,fix rhs)
| Subtraction(lhs,rhs,_) -> Subtraction(fix lhs,fix rhs)
is there any way that would allow me to do something like
match exp with
| Addition(lhs,rhs,_)
| Subtraction(lhs,rhs,_) -> X(fix lhs,fix rhs)
where X be based on the actual pattern being matched
