Hi, I'd like to do something like this -

Instead of doing this -

f x = case x of 1 -> "One" 2 -> "Two"

I'd like to do this -

v1 = 1 v2 = 2

f x = case of v1 -> "One" v2 -> "Two"

Is that possible?

Pattern matching against expressions is not possible, except in the very very limited case of n + k patterns, so no. Bob
