[GvR] >Darn. I wished you'd said something earlier -- I put this in PEP 237 >weeks ago. So many peps and so little time. Following the discussion of peps like this is a bit of a strain when I really don't care what division return. I'll try to be more proactive about new pep revisions in the future. >Does Jython generally try to follow Python's command line options? We try to. -i, -S, -W, -v and -c are the same. A very recently added -E options have a different semantic but that is a bug. In addition we have the options -D, -jar, --help and --version. >Would it make sense to define a Jython property for the division >behavior? That would work. >Then I could change the syntax to -Ddivision=old, >-Ddivision=warn, -Ddivision=new. That's a bit long, but acceptable. Our normal property names are a lot longer: -Dpython.security.respectJavaAccessibility=false -Dpython.options.showJavaExceptions=true because there are situations where the jython properties must live in the same namespace as the properties for java, corba etc. As a practical solution, -Ddivision=warn world work fine. regards, finn
