In cruby there is the gem binding_of_caller which can provide the calling object for different levels of the calling stack
\ne.g.
\n
binding.of_caller(2).eval(\"self\")
\n
Can I get this info also for mruby ?

I can think of two things.
\n
\n
If you are using the mrbc command, the required -g switch is not specified.
\n
The mrb_proc_get_caller() and mrb_binding_new() used by mrb_binding_of_caller() do not support any level of caller.
\nThey must be extended to accept ci arguments.
\n
\n
And, there was a mistake in #6072 (comment).
\nSince the current ci needs to be removed, the range is 0 <= caller_level < (mrb->c->ci - mrb->c->cibase) and is obtained as mrb->c->ci[-1 - caller_level].
