cpython-lru_cache-weakref: Python/compile.c annotate

annotate Python/compile.c @ 13402:7fbdb581838f legacy-trunk

Fixed unicode() to use the new API PyUnicode_FromEncodedObject(). This adds support for instance to the constructor (instances have to define __str__ and can return Unicode objects via that hook; string return values are decoded into Unicode using the current default encoding).
