Re: [Chicken-users] The point of 'provide'

[Rob Roland]

I'll admit to being entirely new to this before I reply, but it looks like ##core#require-extension (compiler.scm) is calling ##sys#do-the-right-thing (eval.scm).

##sys#do-the-right-thing is calling import.  Line 1233:

         `((import ,id))    ;XXX make hygienic

I believe the attached patch may do what you mean for it to do.  This is based off the 4.3.0 tarball.

Thanks,

Rob

Specifically, ##core#require-extension should be calling ##sys#import
(which *is* a procedure) rather than plain import.  Unfortunately,
I cannot find the definition of ##core#require-extension.
