Using lpeg on codepad?

[Randy Kramer <rhkramer@...>]

Can lpeg be used on codepad?  How?  I get a bunch of error messages 
(below) when I issue 'require "lpeg"', so I guess the lpeg module isn't 
present in codepad.  Is there a (simple) way to add it?

If not, is there something else more or less like codepad that I can use 
to quickly run snippets of lua with lpad for learning purposes?

(I've done some googling for things like [codepad 'require "lpeg"'], but 
so far have found nothing useful.)

require "lpeg"
