Research direction

Start by reproducing the compile failure from src/components/MSTQuery/mstquery.py and trace the import chain through mstat/record.py, enum.py, types.py, and _collections_abc. Check how Transcrypt handles these standard-library imports and whether the failure is specific to enum support. Done means the reported package compiles successfully with enum.Enum, or the supported limitation is documented.

Description

PRIO: 2 want STATE: under consideration

I'm not sure if I'm missing something, but does Transcrypt support the enum module in the standard library?

I'm getting this error when trying to compile a package that uses enum.Enum:
