in thread Accessing Arrays and Lists

Just to clarify. Parens immediately after a function are taken as delimiters for the argument list (as you rightly explained) --- but that has nothing to do with Perl's prototypes:

sub foo { # no prototype here
    return ('a','b','c');
}
# print (foo)[0]; # same error
print +(foo)[0];

I also show the unary + op as a better generalization of your last example --- it disambiguates without imposing numeric context.

Of course you're right.

I was thinking of the situation where the prototyping of print (which is the prototyping I meant, not the prototyping of stat) where it treats a function call as a filehandle. I know I've been nailed by that one before. (Although annoyingly i cant think of an example at the minute. Anybody knows of one please post it for the record)

Oh and thanks, I had forgotten the + trick.
