Re: Ang.: Will guile support R7RS terminating "equal?" in the presence of cycle?

It's a type system implemented using guile-log!

By the way, I do not think the overhead is that dramatic. I guess that 
guile's equal would be any slower with this feature added. you typically
does a circularity check via a hare/turtouse pair and when circularity is
found one adress the issue in some way, what might be needed now is to
hook into this code and make sure that rnr7 logic is implemented for that
one version.

Yes, of course.

Typed Guile?  Did I miss something?  :-)
