static VALUE

{
    const rb_cref_t *cref = rb_vm_cref();
    VALUE ary = rb_ary_new();

    while (cref) {

    }

    return rb_funcall(ary, rb_intern("uniq"), 0);
}

Returns an array of all modules used in the current scope. The ordering of modules in the resulting array is not defined.

Example

module A
  refine Object do
  end
end

module B
  refine Object do
  end
end

using A
using B
p Module.used_modules

produces:

Example

[B, A]
