Here is a quirk of the Ruby language that I discovered a few weeks ago.

Method names can not contain a period character.

When I do puts method_name inside #respond_to_missing?, it outputs begin, so it looks like it's treating self as if it were a Range.

This is the RSpec output:

An error occurred while loading ./spec/value_semantics_spec.rb.
Failure/Error: first_letter = method_name[self]

SystemStackError:
  stack level too deep
