Hi, what does the underscore character mean in this debug output?
159:37 5 (delete ((3 . "c") (((2 . "b") (()) 1) (5 . "e") (()) 1)
2) 2)
163:49 4 (delete ((2 . "b") (()) 1) _)
152:9 3 (delete _ _)
86:11 2 (skew _)
64:6 1 (horizontal-left-link? _)
46:11 0 (left-tree _)
Knowing the value of those parameters would be super helpful here, but
for some reason they have been replaced by underscores.

My guess would be that those values are being garbage-collected. Since _
is the pattern for matching an arbitary value, it is used to denote a
garbage-collected value.

Ok, okay. Is there some way to affect that? Perhaps I have to use some
debug printing or stop points to see those values?

I'm finding you get more info if you "guild compile -O0 file.scm" your problematic code files prior to debug session.
