19:13 eli: mithos28: The usual answer is that the REPL is a priceless tool for interactive development, but it should not be used for proper code, hence the banishment of `load' and the use of modules & `require' instead.
19:14 (join) jeremyheiler
19:14 eli: AFAICT, even the r7rs people who really wanted to keep the repl at all cost did so by tricks like "procedural macros -- what's that?  Oh, look, there's a giant pink alligator behind you!".
19:14 eli: (For a rather weak value of "even", that is...)
19:15 mithos28: I'm not sure I get what you mean about r7rs
19:16 mithos28: I've been trying to follow it, but get bored when they have trouble deciding on how = and eqv? work
19:16 eli: :)
19:16 eli: The main point is that telling them that the repl is useful but not sacred is ... dangerous.
19:17 eli: IIRC, they started with a bunch of arguments about these issues that lead to bringing back the fexpr ghosts.
19:17 eli: Stuff like (define (foo) (bar)) and later defining `bar' as a macro.
19:17 mithos28: In the repl or in a module?
