As a side note... that sig will not do the behavior you've described. You instead want this:
sub myprint([EMAIL PROTECTED], +$file is IO:File is rw ::= IO:STDOUT) {...}
The named parameter +$file has to go behind the positional [EMAIL PROTECTED] in the signature, but still goes _before_ [EMAIL PROTECTED] in the actual call.
