Perl allows barewords or strings (which are basically the same, except that a bareword comes without quotes, hence, "bare") as invocants:

File::Path->import(...)
[download]

is the same as:

"File::Path"->import(...)
[download]

and

my $pathtool = "File::Path";
$pathtool->import(...)
[download]

and all three translate to:

File::Path::import("File::Path",...);
[download]
