# Redefine native symbols with a new name as a workaround for
# exporting them in `//third_party/bazel_rules/rules_proto/proto:defs.bzl` with their original name.
#
# While we cannot force users to load these symbol due to the lack of a
# allowlisting mechanism, we can still export them and tell users to
# load it to make a future migration to pure Starlark easier.

"""Lovely workaround to be able to expose native constants pretending to be Starlark."""
