The function_args were two Fixnums and one String, after this you have 
"12" and " 14" instead of the numbers.

So you'd better put the args in an array (before they become Strings) 
and 'Marshal.dump array' this and later

Klass.send function_name, *Marshal.load(function_args)

We should use eval when there is another way.
