Trying to identify what's breaking my system in the syntax-case branch, I found a bunch of around methods in ASDF.
IIRC once upon a time we had removed all the :AROUND methods on exported generic functions, on the grounds that they could unpredictably interact with programmers' extensions.
I think we experimented with using a bespoke method combination method to allow ourselves to have our own around methods and "arounder" methods for programmers.
Even more vaguely, I think I remember that the method-combination extension didn't work reliably on all implementations, so it was stripped out. But I thought when that happened, we tried to excise the use of method combination in ASDF.
Am I hallucinating this?
I'd be grateful to anyone whose memory of this stuff is better.
thanks, r
