"""
|
||
|
|
This file ensures that only types are exported from the .d.ts files, not as
|
||
|
|
values. dts-bundle-generator seems to mess this up: things that were only
|
||
|
|
exported as types from `ffi.d.ts` get exported as values here.
|
||
|
|
|
||
|
|
It also adds deprecation notices to the type exports from pyodide.d.ts that
|
||
|
|
would otherwise be missing them.
