In this case Ian (for whom I have a great deal of respect) is simply
wrong. I know because I did it. Of course, it wasn't a port - I
implemented the underlying language of an earlier version from scratch
before I lost interest.

Injecting methods into the object class is a tactical decision. There
are a lot of things that make Ruby more suitable than Python for
writing embedded DSLs; that is only one of them. Compare Rake and
Scons - the Ruby and Python embedded DSL build systems that are
intended to replace Make, Ant and similar external build DSLs. You can
see the difference in fluency.
