Hello,
obviously, Hugs thinks that =- is a special operator. In Haskell you have the ability to define your own operators, so it would be possible to define an operator =-. I would suggest that you always put spaces around the = in declarations.

Hello, thank you for fast reply. Ok, but what is the semantic of '=-' ? If it's an operator, it should have some impact (right term?).
The semantics are whatever you define them to be: (=-) x y = doSomeFunkyStuff x y Note that this also introduces problems with comments, a common mistake people make is to not put a space after the -- comment symbol, so they may end up with: --| something The compiler then interprets --| as an operator.
