[slime-devel] SLIME's readline problem?

[亀田馬志]

Thank all you guys for the advices.

I see. Macroexpansion before compilation. Then, at that moment,
macro-defined couldn't find function-defined...
I never imagined that. I appreciate you all to telling me that.

I will check how to use eval-when. Thank you very much.

Also, C-u RET solves reader macro issue.

Thanks a lot.
