04:02 PM Ruby Bug #22197: Backtraces show methods which do not exist

In CRuby implementation terms we'd get the original method module with something like:
```c
const rb_callable_method_entry_t *me = cme;
// (1) unwrap an explicit alias entry, if present
while (me->def->type == VM_METHOD_TYPE_ALIAS) {... Eregon (Benoit Daloze)

03:58 PM Ruby Bug #22197 (Open): Backtraces show methods which do not exist

```ruby
class Parent
def original
puts caller_locations(0), nil
end
end
class Child < Parent
alias_method :alias, :original
end
Child.new.alias
module Original
def original
puts caller_locations(0)

09:20 PM Ruby Misc #22192: Clarify the scope of default visibility changed inside a block

TruffleRuby also behaves like CRuby here.

There should already be some ruby/spec for that. Eregon (Benoit Daloze)
