I'm new to Haskell and wondering why this restriction?

For example (from LYH):

infixr 5 :-: data List a = Empty | a :-: (List a) deriving (Show, Read, Eq, Ord)

Not a committee member, but there is a similar restriction (dichotomy, rather) with 'functions' (first char lowercase) and 'constructors' (first char uppercase), so mirroring it to infix operators/constructors seems reasonable.
