Guiles debugging has been a nightmare in the 3.x series. Which is rather surprising since it was probably the easiest scheme to debug in the 1.x days.
It got so bad I moved to racket as my daily driver.
Even better than PLT Scheme with Dr. Scheme, now Raket has ever been?
I have my doubts, given its age.
Can you say more? Guile's the only scheme I've tried (attempts at packaging for Guix). Debugging has been difficult, but I figured it was me struggling with new tools and API. Does racket have better facilities for introspection or discovery at the REPL?
