"""Internal re-exports of builtin symbols.

We want to use both the PyInfo defined by builtins and the one defined by
rules_python. Because the builtin symbol is going away, the rules_python
PyInfo symbol is given preference. Unfortunately, that masks the builtin,
so we have to rebind it to another name and load it to make it available again.

Unfortunately, we can't just write:

```
PyInfo = PyInfo
```

because the declaration of module-level symbol `PyInfo` makes the builtin
inaccessible. So instead we access the builtin here and export it under a
different name. Then we can load it from elsewhere.
"""

# Don't use underscore prefix, since that would make the symbol local to this
# file only. Use a non-conventional name to emphasize that this is not a public
# symbol.

BuiltinPyInfo = PyInfo
