This reverts commit d18d388b1bbf4ba9e50fec6e49087c13a40a2d6c.

This fixes this compilation error:

This could probably be handled similar to https://github.com/ariovistus/pyd/blob/cb78f99f1853f0f14dbba950d7500d76cbeada63/infrastructure/pyd/func_wrap.d#L800 by casting away the return.

Thx and sorry for the trouble. A new tag would be even nicer. :)
