The point is that the Haskell tokeniser treats any consecutive sequence of the symbols !#$%&*+./<=>?@^|-~ as a single operator token. This occurs regardless of whether a definition exists for the operator.
More generally, the tokenising phase is unaffected by whether or not an operator, constructor, identifier etc is defined. A specific sequence of characters will always produce the same sequence of tokens regardless of what definitions exist.
Thank you, that is the problem i am wrestling with. -Philip
