Today: supported overflowing in conversions and left bit shift; inlined Long values; removed some unneeded parentheses in the generated py file. Next time: • Remove wrappers like toLong and kotlin_Int for some numbers (probably research NumberConversionCallsTransformer). • For Long, there are still calls like

._and

,

.xor

,

.equals

instead of plain operators: research why. • Maybe something else related to signed integers, but for now I don't see other tasks here. • Maybe start with unsigned integers.

The factorial looks like working, right? (didn't run yet)

Yep, factorial is working. I'll commit this the next time along with arithmetics if you don't mind
