That looks like a typo, though they may have actually wanted the quotes
and commas in the strings.... if you run that under -w, it'll complain.
By the way, have we mentioned that you should always use strict.pm and
the -w switch? =o) lol....

qw is the "Quote-Word" operator for perl. c.f. perldoc perlop
qw takes a list of whitespace-delimited strings and quotes them as if
they were each in singleticks. For example:
@array = qw / a b c d e /;
creates an array of the alphabet's first 5 letters.
The slash isn't magical here; it's just one possible bounding
character. You can use matching pairs () {} <> [] or other things like
/ if those aren't convenient.
So, to paraphrase the above,
@array = qw( stuff moreStuff evenMoreStuff );
makes an array of those three elements, but the literal value above
would yield:
"stuff",
"more
stuff",
"even
more
stuff"
Notice that the quotes and commas are part of the strings, and that
"even more stuff" got split into three seperate elements of the array.
Does that help?
Is that the actual code you're looking at?
If not, post it, and let's take it apart! lol....
