It's hard, you must create additional wrapper that exposes simpler type

Only through macro ATM, I believe. Note that case statement body does NOT

Python actually provides a Python.h that you can convert to a Pascal unit.
But inside, it includes a bunch of other header files and conversion might
be a tedious task. If you made it, though, simply call:

Check the one here instead:

It depends only on FPC units. I guess you're looking at examples from

The unit is part of LazUtils package. It has no dependency on other packages
but indeed can't be used as a standalone unit, you need other units from the
