Re: [Texmacs-dev] GNU Guile 3.0.0 released and some suggestions for future GNU TeXmacs

[Massimiliano Gubinelli]

Last year I experimented a lot with a Guile 2 port. As soon as you have some 
time you could give it a look and we could try to use it as a blueprint for a 
Guile 3 port. Maybe the JIT will make it possible to disable compilation of the 
files (which is where I currently experience most of the bugs) since eval in 
Guile 3 is as fast as in Guile 1.8 (as they say). Of course compilation (if we 
can make it work) will make bootstrap faster, which would be a great plus.
