Compile-time (ASDF:COMPILE-OP) error about static-dispatch HOT 2 CLOSED

Are the source files being loaded serially or in parallel? The error occurs in combinations.lisp which, according to the ASDF system definition, should be loaded after the file acombin.lisp where (setf combination-function) is defined. Is it possible that your system is compiling all source files first and only loading them after they have all been compiled?
I've added :serial t to the main src module in the system definition, in the latest commit. Check whether that makes a difference.

Sorry about the slow response @alex-gutev. Indeed, the issue is that in my environment the code is fully compiled before loading, and the old .asd system definition allowed parallel compilation that broke the actual dependency chain. Thanks for the fix!
