Patches? I face a few problems.
What about this problem, and what could be a workaround?

I implemented some methods in TCustomVariantType (subversion of today), but
there are still quite some missing. Please test to see if it gets you any
further.
thanks, I took&compiled only the new variants.pp into the RTL
Then VarPyth.Import worked and walking/calling the Python object tree works
now.
But any assignments to or from Python and argument passing fail.
pp := Import('pp');
pp.x.y(); // works!
i := pp.f(); // EVariantTypeCastError (i:Integer or LongInt)
This needs investigation.
pp.a := 99; // TCustomVariantType.RaiseDispError not supported
pp.f(6); // TCustomVariantType.RaiseDispError not supported
These are caused by what is still missing in custom variants :-)
Does it help to take more of current SVN ? or a principal problem with
Typecasts?
I'll need to check what is still missing. The variants unit could use some
cleaning up.
Michael.
