The only PL/I compiler I have access to is, somewhat ironically, the
Multics PL/1 compiler. It is largely self-hosting; more details can be
found here: https://multicians.org/pl1.html (Note Doug's name appears
prominently.)

I imagine most of it is legacy code in a mainframe environment, similarly
to COBOL. I can't imagine that many folks are considering new development
in PL/1 other than in retro/hobbyist environments and some mainframe shops
where there's a heavy existing PL/I investment.
