pass the test of float, but got "uninitialized constant Kernel::Foo (NameError)" with the latest mruby

Dear Dr. Dorier,

Thank you for your simplification in mrubybind using C++14 variadic templates.
It is great!

I want to use mrubybind with the latest mruby.
I fixed test/test.sh to pass the test of float.
However, I got an error of "uninitialized constant Kernel::Foo (NameError)" as

$ git clone https://github.com/mruby/mruby.git
$ cd mruby
$ rake
$ cd ..
$ git clone https://github.com/mdorier/mrubybind.git
$ cd mrubybind/test
$ MRUBY=../../mruby make test
          :
Testing class ... (unknown):0: uninitialized constant Kernel::Foo (NameError)
[ERROR] exit status is not 0 [134]
          :

Can you please fix it?

A change in bind_class() in mrubybind.h
from MRB_SET_INSTANCE_TT(tc, MRB_TT_DATA);
to MRB_SET_INSTANCE_TT(tc, MRB_TT_CDATA);
could not cure the error.

Sincerely,
