Thank you very much for reminding me. I have been sloppy.
It should have said static type checking.

Thank you very much. It is really a very elegant piece of code :-)

Your module tackles type checking, I
tried to execute arbitrary code before
and after function execution to realize
runtime assertions.
I wonder

Actually, Python is strongly typed. It's just dynamically instead of

Hi George,
it would be nice to see how you have tackled

Maybe we will have a checker
module in Python one day... ;-)

That should really be done through having those classes inherit a

Hi Stephen
I have not read anything about the
framehack lambda replacement yet,
but I do compile the pre- and
postconditions. Syntax erros e.g.
will be raised if the module
is compiled. Although I must admit
that your code snippets look more like
compiled code ;-)
