Doh! (Note to self: wait a little while longer before
replying as often all will be made clear.)
I actually did remember this back in the t
at you recommend which are good in describing
these uses and behaviors? I've been using the O'Reilly camel book called
Programming PERL but it's pretty old (first edition).
