"""Internal re-exports of built-in symbols.

Currently the definitions here are re-exports of the native rules, "blessed" to
work under `--incompatible_load_python_rules_from_bzl`. As the native rules get
migrated to Starlark, their implementations will be removed from here.

We want to re-export a built-in symbol as if it were defined in a Starlark
file, so that users can for instance do:

```
load("@rules_python//python:defs.bzl", "PyInfo")
```

Unfortunately, we can't just write in defs.bzl

```
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 defs.bzl and export it there under
the original name.
"""

# 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.
