Well, depends on how you define `builtins' :)  Do you mean functions
in the builtin module, or C builtin functions?  Or are you looking for
a convenient one-liner?

Essentially the unhexlify I posted uses only C builtin functions,
e.g. [].append, strop.atoi, range, len, chr, strop.join.  I don't
remember if anybody came up with a nice one-liner when the thread was
debated eons ago.

Cheers,
