Can someone show an example of this defsubst in use? I'm not sure I understand what it's for.
To the best of my understanding it has two effects: 1. it allows reliable inlining on compilers that do not respect inline declarations. 2. it allows the expansion to utilize the lexical context of the call site. Consider: (defmacro foo () :global) (declaim (inline bar1)) (defun bar1 () (foo)) (defsubst bar2 () (foo)) (macrolet ((foo () :local)) (values (bar1) (bar2))) => :GLOBAL, :LOCAL Cheers, -- Nikodemus
