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. By default, make_varname() returns a string of 10 characters, but if a numerical argument between 3 and 20 is passed to it, a string of that length will be returned. Arguments smaller than 3 are rounded up to 3; arguments greater than 20 are rounded down to 20.
