Yes; to fix. > Andy, I think you wrote "FIXME: use module binders instead" in > compile-tree-il.scm, what does that mean? For global refs, the current code does a lookup every time a function is called, where instead it should allow the variable to be cached the first time it is looked up. The way to hook into the process of caching a variable for lookup is module binders. They aren't documented though. Search for "binder" in ice-9/boot-9.scm and in modules.c.
