Could we also agree a suitable acronym for all Perl Questions and replies.
I suggest [BPQ] for Beginners Perl Question.
That way people can set-up an email folder and move them using a rule.
This would go at the start of the subject line.

Ooo, a bibliography at the end of the specific advice -- that's a *great*
idea for a beginners list. We should make that a convention :)

The short answer is no.
The slightly longer answer is that so far no one has made perl run

keyboard input char by char and time the difference between each keystroke.

The "my" keyword makes a variable local. It's a scoping mechanism, and is
primarily used inside function definitions to keep the namespace
uncluttered.

The perl documentation (perldoc -f my) has this to say about the perl
builtin "my":
A my declares the listed variables to be local (lexically) to the
enclosing block, file, or eval. If more than one value is listed, the
list must be placed in parentheses. See Private Variables via my()
