Hi!

I've seen in plan9port there's a commit allowing @s in filenames:

commit ac487c754e009b0f3c01c2a8ad5bda2143da4a6b
Author: Russ Cox <rsc@swtch.com>
Date:   Wed Dec 30 14:42:47 2020 -0500

    acme: allow @ in file names

    For upspin and other tools that put email addresses in names.

In the Go module paths this is used in path names actually to delimit the v=
ersion. Here's a patch for this, would be great if it could get merged!
