Need Help??

Since I believe he is talking about $method being a string, wouldn't the first version need no strict 'refs', and a leading ampersand?

for(split(" ","tsuJ rehtonA lreP rekcaH")){print reverse . " "}print "\b.\n";

No: `perl -Mstrict -le "sub P::p{print 'p'};my $p=bless {},'P';my $m='p';$p +->$m;"` [download]	[reply] [d/l]

I acknowledge that this works, and runs under "use strict"; but how is $m not a symbolic reference? I'm a little confused here. `for(split(" ","tsuJ rehtonA lreP rekcaH")){print reverse . " "}print "\b.\n";`	[reply] [d/l]

Yes. It is a symbolic reference (a name instead of a "real" reference). Yes. It still works even under "use strict 'refs'". That's the way it works, and always has. -- Randal L. Schwartz, Perl hacker	[reply]
