In, e.g., Opera, it isn't a function, and calling it as one gives an error. Opera is completely compliant with ECMA 262 on this. In Firefox, calling a regular expression as a function is equivalent to calling the "exec" method on the RegExp object, i.e., it's a redundant feature. I guess it's an old Netscape JavaScript leftover. (Just came by to look at the 3d graphics. Nice! :) Common sense doesn’t tell me that a regular expression can be called as a function.
