Subject: [ruby-core:57297] [ruby-trunk - Bug #8870] Method-Missing breaking	irb


Issue #8870 has been updated by bjhaid (Ayodele Abejide).


I do understand that its bad to use method_missing in the global space, but the behavior should be space irrespective of scope

This works:
2.0.0-p247 :002 > m "2","a","b"
 => ["2", "a", "b"]
2.0.0-p247 :003 > (m "2","a","b").class
 => Array

This breaks:
2.0.0-p247 :004 > def method_missing m,*args; args.class; end
 => nil
2.0.0-p247 :005 > m "2","a","b"
/Users/bjhaid/.rvm/scripts/irbrc.rb:32:in `initialize': can't convert String to Fixnum (String#to_int gives Class) (TypeError)
