So here's round one.
Quite a few items in slib.scm are already in guile.init, and so we can
just drop those. There are some other bits that I wanted to present
for discussion and double-checking.
As background, at the point when any of this code executes, the
current module is (ice-9 slib).
A minor difference regards output-port-width. The version in slib.scm
returns 80 where the version in guile.init returns 79.
A more significant question regards evaluation. In slib.scm we have:
(define-public slib:eval
(lambda (x) (eval x slib-module)))
(define defmacro:eval
(lambda (x) (eval x (interaction-environment))))
where guile.init has:
;;; SLIB:EVAL is single argument eval using the top-level (user) environment.
(define slib:eval
(if (string<? (scheme-implementation-version) "1.5")
eval
(let ((ie (interaction-environment)))
(lambda (expression)
(eval expression ie)))))
(define defmacro:eval slib:eval)
The major difference here is that SLIB's slib:eval evaluates in
interaction-environment rather than the slib module. It looks like
the current defmacro:eval behaviors are the same.
