Re^4: regexp list return 5.6 vs 5.8

[Sixtease]

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')), "}";)

Strange indeed.

michael$ perl t.pl
{{}
{}
{123}
{123}

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 ];
}

produces

[ ]
[[]

[]
[]
