Hello Monks,

Below are some snippet codes that i don't understand the behavior, please help:

First case: 

my $foo = "weird123";
my $result = $foo.($foo =~ s/123//?$foo:"");
print $result; # "weirdweird"

[download]

Second case:

my $foo = "weird123";
my $result = "".$foo.($foo =~ s/123//?$foo:"");
#or: my $result = $foo."".($foo =~ s/123//?$foo:"");
print $result; # "weird123weird"

I already had a discussion with one fellow monk, he thought that the "" is forcing the left side of "." executed first before the substitution. He was also not sure so i ask this to make us understand better.

Thanks in advance!
