{
return send_internal_kw(argc, argv, recv, CALL_PUBLIC);
}
Invokes the method identified by symbol, passing it any arguments specified. Unlike send, public_send calls public methods only. When the method is identified by a string, the string is converted to a symbol.
Example
1.public_send(:puts, "hello") # causes NoMethodError
