I have clozure working fine in aquamacs 3.5 with "Version 1.12 (v1.12-dev.3-125-g595a5cf4) DarwinX8664" and mojave 10.14.6, so pretty sure this is a catalina/ccl issue independent from slime. There are several...

Hello, I believe the code that you changed simply modifies the declaration for the step-by variable `#:LOOP-STEP-BY-6`and this is what you achieved (now getting the compiler warning). loop-constant-fold-if-possible simply warns...

I believe a good explanation is the following: ```lisp (defun test () (let ((var 0)) (declare (type (and number (real (0))) var)) (+ 23 var))) ```` in ccl this compiles...

In summary i believe your fix is correct, It just doesn't create the type-error you expected

@phoe I knew all that. I tried to make a connection to the loop problem with the `by 0`. if you verify carefully the macroexpansion, you see the ```` (LET...

I think you missed the beginning: * `(loop for i below 10 for j by 0 collect (list i j))` works fine in ccl, but is against the spec (the...

If a macroexpansion-time error is kosher, perhaps we it is easier to change `loop-constant-fold-if-possible form` to raise an error instead of warning as it does now (and do the change...

@PuercoPop @digikar99 @phoe #307 solves this, please check
