[Haskell-beginners] Question on syntax

[Rohit Sharma]

All,

I started learning haskell very recently and have a question on the pattern
matching style for lists.

In the below snippet i.e. "(x:xs)" why do we went with round braces and not
square? I know we are using cons that tells this is not a tuple but would
it not make more sense to write something like [x:xs] instead of (x:xs), i
thought round braces was used for pair/tuples?

safeHead [] = Nothing
safeHead (x:xs) = Just x

Thanks,
Rohit
