Haskell camelCase

Haskell has support for function_names_with_underscores. Why the fuck do people use PIG DISGUSTING camelCase?

I don't see how you would support spaces in symbol names without some kind of delimiter, or greatly crippling the rest of the language (like that double spaces idea that someone once posted here). CL does support both variants:
this-is-a-symbol-name
|this is a symbol name|
