Re^4: regexp list return 5.6 vs 5.8

Wow, so the [[] was not a typo? I thought it was. I still don't understand how it could have got there! What does it print when you use different delimiters? (like print "{", scalar(test('abc')), "}";)

use strict; use warnings; print "Just Another Perl Hacker\n";

Strange indeed. `michael$ perl t.pl {{} {} {123} {123}` [download]	[reply] [d/l]

Putting the call inside a `@{[ ... ]}` construct does something different. `print "[@{ [ scalar test('abc') ] }]\n"; print "[", scalar test('abc'), "]\n\n"; print "[@{ [ test('abc') ] }]\n"; print "[", test('abc'), "]\n\n"; print "[@{ [ scalar test('123') ] }]\n"; print "[", scalar test('123'), "]\n\n"; print "[@{ [ test('123') ] }]\n"; print "[", test('123'), "]\n"; sub test { my @rv = $_[0] =~ /^([0-9]+)$/; return @rv[ 0 .. $#rv ]; }` [download] produces `[ ] [[] [] [] [123] [123] [123] [123]` [download] Running 5.8.4 on Solaris 9.
