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

[Massimiliano Gubinelli]

It would be good to have an automatic test-suite to evaluate seriously the 
performance issues involved in this choice, also in the perspective to 
understand what would be the margin of advantage to adapt the codebase to Guile 
3. 

Do you have some ideas of which areas involve Guile performances seriously?
