(define left-section (lambda (binproc left-param) (lambda (right-param) (binproc left-param right-param))))

I usually create these pages
on the fly, which means that I rarely

It also means that I tend to update them regularly (see the history for
more details). Feel free to contact me with any suggestions for changes.
