Perl allows barewords or strings (which are basically the same, except that a bareword comes without quotes, hence, "bare") as invocants:
File::Path->import(...)
is the same as:
"File::Path"->import(...)
and
my $pathtool = "File::Path";
$pathtool->import(...)
and all three translate to:
File::Path::import("File::Path",...);
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
