perl-String-PerlIdentifier (generate a random name for Perl variable)

String::PerlIdentifier - Generate a random name for a Perl variable.

This module automatically exports a single subroutine, make_varname(),
which returns a string composed of random characters that qualifies as
the name for a Perl variable. The characters are limited to upper- and
lower-case letters in the English alphabet, the numerals from 0 through
9 and the underscore character. The first character may not be a numeral.
