Re^3: use subs

Did I miss something (upd.: yes, I did) or couldn't this be cut down to simply:

use subs 'open';
sub open {
    print @_ . "parameters: @_\n";
    CORE::open(@_[0..$#_]);
}

(I didn't test anything, so I may well be way off the mark.)

Makeshifts last the longest.

No, it can't. The CORE::open does not succeed if you do not hand it a scalar filehandle. use subs 'open'; sub open { print @_ . " parameters: @_\n"; my $filehandle = shift; CORE::open($filehandle,@_[0..$#_]); } sub open2 { print @_ . " parameters: @_\n"; CORE::open(@_[0..$#_]); } my $result; print "Testing open...\n"; print open(TEST),$/; print open(TEST, "test.txt"),$/; print open(TEST, "<test.txt"),$/; print open(TEST, "<", "test.txt"),$/; print $/; print "Testing open2...\n"; print open2(TEST),$/; print open2(TEST, "test.txt"),$/; print open2(TEST, "<test.txt"),$/; print open2(TEST, "<", "test.txt"),$/; print $/; [download]	[reply] [d/l]
