Note to all: the abcl.lisp implementation inadvertenly contains a reference to LCONS*. <https://github.com/slime/slime/blob/master/swank/abcl.lisp#L1086> Recompiling the form via SLIME once things have been loaded works fine. Any chance we can get a standard mechanism to recompile stuff in the implementation to declare that a given thunk should be recompiled once SWANK has finished loading? Back in 2017 or so, @aruttenburg had a patch to some of move the some of the utlities to load before the implementation-specific, but @stastats objected on the grounds that we want the initial load to be as fast and error free as possible. I really don’t want to redefine LCONS* in the ABCL specific code, but that will work for me if no one has a better idea. regards, Mark -- "No, this is not a disentanglement, but a progressive /knotting-into/."
