Is the last two word "lexical scope"?

Path::Class

It appears that some text is missing just before the code, as "dir", "subdir", "parent", and "as_foreign" (NOT the variables) are introduced without explanation. There is also no "use Path::Class;" in the code .

"The Path::Class module, which doesn't come with Perl, gives you a more pleasant interface:

my $dir = dir ( qw(Users fred lib) );
.
.
.
"

3rd paragraph and its code example

Does the italian formed "my_program" in 3rd paragraph mean "show_my_cwd"?
Since the name of example program in code example is "show_my_cwd"

There appears to be text and code missing and/or out of place:

"...Compare that with this security problem:
system "tar cvf $tarfile @dirs"; #Oops!
Here, you've now piped a bunch of stuff into a flintstone command ..."
