I always wonder why so many languages eschew multiline comments. Is it monumentally harder to make a parser that supports it or is this a conscious decision?
It's not too hard, it was just a combination of laziness plus not being able to decide on a multiline comment syntax that looks nice. Anyway I just added it, using {- and -} separators (as in Haskell)
I was just curious since there seem to be a few languages that only have single line comments. But usually it just results in people finding "hacks" so they can make them anyway (like Python's doc-strings) which just ends up being uglier than supporting them natively.
