Hi,

This post is Dedicated to the Memory of Scheme R4RS.
The ISO core standard witness calculation [7.1.1.4]
is the most hated among Prolog programmers, since it
produces false positive for nested (^)/2 occurences.
We show how to use it nevertheless for arrow
functions compilation.

We identified outside-in processing as the culprit
of false positives, the use of inside-out processing
then shows a promissing ability to minimize free
variable. We wish what we have done statically,
could also be done dynamically. But we are facing
serious new rational trees challenges.

Bye
