Topic: matching on variable

Nick Hallstrom (Mar 14 2023 at 19:28):

Is there a way to match where the left hand side of the arrow is a variable? For example

a = 10

when foo is
    ^a -> "Only matches when foo is 10"
    _  -> ""

I think we added guard clauses:
x if x == a -> ...

Oh ya, duh :man_facepalming: I think that should totally work, thanks!
