The real issue however, is that multiple ! arguments are not allowed. >From what I can gather on the forum, the reason is a perceived ambiguity, in that F!T!int could mean F!(T!int) or (F!T)!int. The language already provides tools to disambiguate between them - the first example is how you'd invoke it that way, and the other example is simply impossible in the language right now. -- |
