Re^7: Modernizing the Postmodern Language?

I believe that sub would need to be:

sub FH { our $FH; return $FH }

So does this lead to a use filehandles pragma that will (mostly) work for declaring filehandles by establishing the proper subs?

This `sub FH :lvalue { my $fh }` should do. But I don't have the time to test it in all edge cases. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]

You are correct about needing the `:lvalue` attribute, but if I understand correctly, `my` will create a new scalar every time `FH` is called. Another alternative could be: `{ my $fh; sub FH :lvalue { $fh } }`, using the closure to capture a single instance of the lexical. TIMTOWTDI really works!	[reply] [d/l] [select]

you are right of course, a closure was my initial idea, dunno why I lost it here. FWIW `state` might be an alternative Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply]
