Hi there, i am currently writing a mgem (in C) which wants to work by sending the numeric values (aka mrb_sym) of nested classes, with top level classes thats no issue.

I got a method which takes a class as an argument, i want to serialize that class name as symbols and not strings and send that to another mruby vm which runs in the same process. (presym is enabled)

The receiving side of that method just gets an array of symbols and then walks the object tree till its found and recreates that class.
aka in pure ruby.

klass = Object
path_syms = [:Actor, :Testme]
path_syms.each { |sym| klass = klass.const_get(sym) }

now klass is Actor::Testme

but how can i create that array in the first place?

I'm asking since i've benchmarked it that sending the top level classes as mrb_sym instead of string brings a massive speed boost.
