I certainly appreciate the pain you have gone through
in writing that mail, but I haven't understood about
"perldoc -f my". I went through a book , How to Perl
5, last night. And it says that every variable
declared gets into main, a default package. To avoid
the namespace pollution it says that, its a good way
to hide names from collision.
Tell me if I have misunderstood it.
Well infact if u could send me a a small code which
uses the perl -f doc or the later thing mentioned by
you, would help me a lot.
