I believe the motivating example that persuaded the Language Committee to allow these symbols was --> which is not of course used anywhere in the standard libraries, but is an extremely nice symbol to have available in user code.
Seeing as no library actually defines such a symbol, is it worth forcing an extra space into comments? --| and --^ would be an extremely nice symbols for haddock comments.
We already have to forms of comments: -- and {- -}; why do we need another two? Think of it this way: the "--" defines the comment, and then we use the "|" or "^" to indicate to _haddock_ to interpret this differently. I don't think we need to special-case symbols starting with "--" just to avoid having to put a space in to delimit the comment indicator and the markup indicator. That said, I have a use for --> as a symbol... if it wasn't that I'd also want something like -- to follow suit, and as such it'll just be easier to use something like .->. and .--. (for creating directed and undirected edges respectively in graphs). -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
