Sorry, something went wrong.
…ts (pythonGH-158825) When a module attribute was a lazy import placeholder, module attribute lookup called the module's __getattr__ before resolving it. This was needed while lazy from-imports published placeholders on the source module. That no longer happens, so the check only affected the module's own lazy imports: a catch-all __getattr__ hid them, unlike eager imports. Resolve the placeholder directly.

When a module attribute was a lazy import placeholder, module attribute
lookup called the module's getattr before resolving it. This was
needed while lazy from-imports published placeholders on the source
module. That no longer happens, so the check only affected the module's
own lazy imports: a catch-all getattr hid them, unlike eager imports.
Resolve the placeholder directly.
