The question is, is there some very important reason you can't do this?
firstCoord (P x _) = x

In Haskell, a data constructor can be used partially applied: data Pair a b = P a b
f = P 1
however, I cannot do "partial pattern matching", e.g
firstCoord (P x) = x
does not work.
I guess a very important reason must exist why this is the case?
