Sorry, I mean the three dots '...' that seems to be what the

That just means it can take whatever arguments. The
documentation is just saying it is callable with anything; the

variadic argument list, again meaning it can take anything.
(The reason isCallable does it though isn't to actually take
multiple arguments, it is so it can take any *kind* of
argument; a bit of a hack.)
Ah right, I get it. Thanks.
