[Zope3-dev] type checking in Zope 3

[Baiju M]

Hi,
    What is the preferred way to check type in Zope 3.
I got lots of output for these two commands:
  $ find . -name "*.py"|xargs grep "from types"
  $ find . -name "*.py"|xargs grep "import types"

In some places type(module) is used. See this patch, a single
-1 is enough for me to not commit it.
A commit for simple code beautification is bad :)

Regards,
Baiju M
