Hear me, o people!

You cannot be serious. Please knock it off.

  I should also note that a pure Lua module will have no such restriction.
So it's possible to have this:

        local syslog = require "6CC24CA3_0D40_550D_9B0F_EF54C94C54C1.syslog"

        local xdg    = require "13DC8997-46AB-54E2-9BC4-10C88CFAC5D4.xdg"

        syslog("debug","this is here")
        syslog('debug',"desktop=%s",xdg.DESKTOP_DIR)

where you have two styles of UUID.  Oh, and heaven forbid someone attempt to
do:


        local syslog = require "6cc24ca3_0d40_550d_9b0f_ef54c94c54c1.syslog"
        local xdg    = require "13dc8997-46ab-54e2-9bc4-10c88cfac5d4.xdg"

        syslog("debug","this is here")
        syslog('debug',"desktop=%s",xdg.DESKTOP_DIR)

  On some systems (with case-insensative filenames) this will work ... on
some, it won't ... good times.

  -spc (For the record, I don't think using UUIDs as a namespace is a good
        idea ... )
