+Subject: [PATCH] cli: import Annotated from typing, not typing_extensions
+
+Upstream-Status: Backport [https://github.com/hardbyte/python-common-expression-language/commit/212cf00c48b6dd1a7fe35ae092eee414b1825f01]
+
+cel/__init__.py imports cel.cli, which imports Annotated from
+typing_extensions. typing_extensions is not a declared dependency; it
+used to arrive transitively through typer, but typer 0.21.2 dropped it,
+so `import cel` fails with "No module named 'typing_extensions'" in any
+clean environment. This reproduces on every architecture, not just
+riscv64.
+
+Upstream fixed it in 212cf00 ("Fix `import cel` failing in a clean
+install", #44, released in 0.10.0) by importing Annotated from the
+standard library's typing module (Python >= 3.9; the package requires
+>= 3.11). This backports the python/cel/cli.py hunk of that commit.
