Sorry for the late reply, I didn't see your message, and never received
the pings I see on issues.guix.gnu.org.
Here is the output of size on bin/python:
text data bss dec hex filename
2072 704 8 2784 ae0
/gnu/store/bcggflp7zszpazgk8qa4sr0kmp5a67pg-python-minimal-3.9.5/bin/python3
Same, for lib/libpython3.so:
text data bss dec hex filename
1154 576 8 1738 6ca
/gnu/store/bcggflp7zszpazgk8qa4sr0kmp5a67pg-python-minimal-3.9.5/lib/libpython3.so
Same for lib/libpython3.9.so.1.0:
text data bss dec hex filename
3614304 254928 139896 4009128 3d2ca8
/gnu/store/bcggflp7zszpazgk8qa4sr0kmp5a67pg-python-minimal-3.9.5/lib/libpython3.9.so.1.0
But I noticed another file gained a lot of weight:
lib/python3.9/config-3.9-x86_64-linux-gnu/libpython3.9.a weighs 39MB,
whereas on master (for 3.8.2) it weighs 6MB. Here is what size has to
say:
text data bss dec hex

I had to remove the file name it comes from, because of width issue
in email, but I don't really understand what size does, so I don't know
if that's relevant or not. Do we need to keep that static library
around?
