Think "hungarian".  Basically, you put the type, clearly described by
a simple string (such as lpsz), before the "real" variable name.

I'm not sure if it makes less sense in C (which has types, so you
introduce a redundancy and a good source for errors into your code),
or in Perl (which doesn't have Strings terminated by Zeros, or any of
the other types, and has typed data, but not variables).

It has the particular advantage that if you need to change types (even 
with compatible assignments), you're hammered.  Either you change the
name (and break old code), or you keep the old name (and describe an
error code, say, as a boolean).

I'd still like to claim that the only use for hungarian notation in
Perl is to write

	$sStr = 'a string';
	$szStr = $sStr . '0';
	$pszStr = \$szStr;

That's &bCheckIfThisIsAnAceFile(), if you don't mind.
