Coverage increased (+0.02%) to 92.37% when pulling 426c59e on Rudolph-Miller:optimize into cc80bb6 on fukamachi:master.

I don't get why this change has to be in. The step could be a symbol or a form.

[rudolph-miller]

with (declare (speed 3) (safety 0) (debug 0)) compiler said step is uncertain.
Can step be symbol or form?

[fukamachi]

Yes, cause advance* is a macro.

You're declaring it compile-time. If the warning disappears by this, it's not important, just you're making it unsafe expansion.

Are there any differences in performance?

[rudolph-miller]

I know it has no influence on performance and it's just matter of compilation time.
I wanna just remove warnings.
Does the change make it unsafer?

[fukamachi]

There must be other warnings in compile-time too. Declaring speed 0 in the macros would work, I think.

[rudolph-miller]

Really?
I can not remove warnings with speed 0 in macros.
Anyway, I can ignore the warnings with compilation time.
