the man page of test(1) mentions "-l string" as string length operator
for -eq, -gt, etc.
but there seems to be nothing in the plan9port's src/cmd/test.c, nor
in 9p.io/sources/cmd/test.c
is there any implementation of this floating around?

Sure, in the research unix releases (e.g. [1]). No idea why it got
dropped en route to today. Further: unknown why someone cared enough
to drop the feature but not enough to fix the man page.
