I'm hitting CLJ-1852 [0] (Clojure-generated class names length exceed file-system limit) with a large core.match expression. I have verified that it is the number of clauses in core.match: compilation works as soon as I reduce it, and looking at `target/` it is actually producing very long filenames a la:
'iddqd$xyzzy$fn__19779$fn__19788$fn__19789$fn__19790$fn__19793$fn__19794$fn__19795$fn__19796$fn__19797$fn__19814$fn__19815$fn__19816$fn__19819$fn__19820$fn__19823$fn__19824$fn__19825$fn__19826.class' However, I don't quite understand _why_ core.match produces such long filenames. The error and filename suggest the problem is deeply nested fn*s. Judging by macroexpand-all it's just a ton of let and try/catch which I'd expect don't compile to fn*s internally (I'm aware of the equivalent between let and lambda but I expect that's not really how it's implemented). I am trying to understand why it's producing all of these nested fns as compiled classes to see if I can somehow work around this (without rewriting the function completely, hopefully!). I've found a similar reproducer here[1]. Unfortunately it doesn't do a better job explaining _why_ the compiler emits that. Any tools for helping me understand the compiler would be helpful. I'm already quite comfortable with JVM bytecode and asm. Is the best way to figure this out just to read Compiler.java?
