[ruby-core:122250] [Ruby Feature#21365] Add `Namespace#eval`

Issue #21365 has been updated by Eregon (Benoit Daloze).


Yep, agreed it'd be far more convenient for testing Namespace.

Why `instance_eval`? The distinction between eval/class_eval/instance_eval does not seem relevant here.

Though of course the semantics should be the same as writing the code to a file + `Namespace#require` so e.g. `ns.eval "def foo = 42"` defines method `foo` on ns' copy of Object methods.

I would like a way to eval code on to a `Namespace` object. Could we add an eval method that _doesn't_ take a binding object?  Writing a new file every time I want to test Namespaces is too cumbersome.

Thanks!
