RE: [Jython-users] Supporting + on Java objects

[Anthony E. <ae...@si...>]

FWIW, the text below would make a good FAQ entry for Java programmers coming to the world of Python wondering about how
Strings work in Python.  Kevin's explanation was right on track and answered the question succinctly.  I am sure that
String concatenation is covered in the Python docs, but I still think it would be good to cover this in the Jython docs,
primarily because a lot of Java code transfers very easily to Python but some of it (such as for(x in y) and String
handling) do not.

Perhaps there are other stumbling blocks which Java developers coming to Jython will experience which could also be
documented better on the Jython site.  What do you think?

Sincerely,
Anthony Eden
