Our cffi-backed tk/tcl implementation is failing the test_idel tests [0] on python3.7, and the failures persist in the 3.8 branch.

Could someone who understands the way it is supposed to work take a look?

There is something tricky about passing unicode strings and kwargs that we don't have right.

This is pure python + cffi + tk/tcl, no RPython needed, no long translation times.

If you wish to help but don't know how to start, let us know, anyone is welcome to pitch in.

Thanks

Matti
