Sorry, something went wrong.
RubyBignum overrode eql_p to delegate to op_equal (==), which accepts Floats and Rationals. In Ruby, eql? must be type-strict: (2**100).eql?((2**100).to_f) should return false. Remove the override so the parent RubyNumeric.eql_p handles it correctly with a getClass() check before value comparison.

Consider moving specs to ruby/spec.
