This is currently possible by using `Symbol.all_symbols`, however it builds a new array every time it's invoked which is pretty inefficient. The main use case for this would be to assist in detecting accidental symbol creation. I have a PR open (https://github.com/ruby/ruby/pull/639) that adds a `Symbol.count` method but this could also be added in the output of `GC.stat`. -- https://bugs.ruby-lang.org/
