In Haskell period (".") is used both to form a qualified name (module.name),
very similar to our schema.object, and it is also a perfectly normal
operator which is defined by the standard prelude as function composition
(but you can re-bind it to any object whatsoever). This is disambiguated in
a very simple way however: Module names must begin with an uppercase letter
while variable names must begin with a lowercase letter.
A related point is that parentheses in Haskell act to group expressions,
but they, and commas, are not involved in calling functions: to call a
function, just write it to the left of its parameter (and it only has one
parameter, officially).
All this might sound weird but it actually works very well in the Haskell
context.
