Subject: [Haskell] Case statement and keyword "otherwise"
Print | View thread | Show original | Report this message | Find messages by this author
Accidentally, I wrote something like:

fun x = case x of 0 -> "zero"; 1  -> "one"; otherwise -> "many"

By "otherwise" I meant "_". Surprisingly, it seems to work how I intended.
Now I don't  understand how - taking into account that "otherwise" has Bool
value True, there must be type error here! Or is this word means something
different when inside a case statement?
