Subject: [bug#45604] [PATCH 1/1] Added magic-enum header-only library as a package.

Hello Anadon,

I have not yet built your package (because I'm currently also handling
another patch), but since you've requested review over at guix-devel,
I'll have a go at it.
For the future please note, that a delay of 2 days does not mean we
haven't noticed you at all.  The manual has the following to say for
committers:

Ehh, somehow the commit message and everything is missing here.  Is
that intended or just misconfigured?

The home-page claims, that it works with GCC>=9.  Have you encountered
any issues with gcc-9 instead?

I feel as though that could be worded better.

Descriptions should be complete sentences and end with a period.
