If an alias uses too few brackets then the statement might be ambiguous and the alias will take longer to parse, might be parsed incorrectly, or might not be parsed at all.
Omitting
both () and {} creates an inherently ambiguous piece of code and there's nothing mirc can do about that. It already does its best to parse statements with fewer brackets (which is why omitting
either () or {} works). For example, how should mirc know that $for() is meant to be the entire condition and not just the first operand? Just because $for() returns $true/$false doesn't mean it should be considered the entire condition: remember there are no real types in mirc scripting.
