Yes, that's a good addition.
For C code it's preferable to pass in a variable length list of strings,
which are then converted into the key names, because it doesn't require
parsing the string. See 'Parrot_ex_throw_from_c_args' (src/exceptions.c)
and 'Parrot_mmd_multi_dispatch_from_c_args' (src/multidispatch.c) for
examples of using C varargs. It would be something like:
PMC*
Parrot_pmc_build_key_from_c_args (PARROT_INTERP, ...)
{
va_list key_names;
va_start(key_names);
#...iterate through the key names to build the key PMC
va_end(key_names);
}
