Would you prefer MRI or YARV then?
As I mentioned above `RubyVM` seems highly confusing for something MRI-specific, and not a general "Ruby VM" namespace.

----------------------------------------
Bug #15743: RubyVM should be renamed to CRuby
https://bugs.ruby-lang.org/issues/15743#change-77461

* Author: Eregon (Benoit Daloze)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: Next Major
* ruby -v: ruby 2.6.2p47 (2019-03-13 revision 67232) [x86_64-linux]
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
My understanding is that `RubyVM` is supposed to only exist on MRI/CRuby, and not on any other Ruby implementation.
In fact, almost all features under `RubyVM` are not realistically implementable on other major Ruby implementations (JRuby, TruffleRuby, Rubinius).

Unfortunately, the name doesn't reflect that it is specific to CRuby, e.g., JRuby/TruffleRuby/Rubinius are also "Ruby VMs".
And as a result it is not clear for many Ruby users that RubyVM is CRuby-specific.

The documentation is also unclear:
```
The RubyVM module provides some access to Ruby internals. This module is
for very limited purposes, such as debugging, prototyping, and research.
 Normal users must not use it.
```

So I propose to rename RubyVM to CRuby.
That way, it is clear for everyone that this module is CRuby-specific.
It's also consistent with the JRuby module, the TruffleRuby module and the Rubinius module.

Proposed migration path:

* Introduce CRuby as an alias of RubyVM on `trunk`, and deprecate the RubyVM constant on `trunk` (for 2.7).
* Remove `RubyVM` in Ruby 3.0.

What do you think?
