RubyVM

        # RubyVM < Object

(from ruby core)
---

The RubyVM module only exists on MRI. `RubyVM` is not defined in other
Ruby implementations such as JRuby and TruffleRuby.

The RubyVM module provides some access to MRI internals. This module is
for very limited purposes, such as debugging, prototyping, and research.
 Normal users must not use it. This module is not portable between Ruby
implementations.
