Yup, I don’t forget LilyPond!

Like I wrote, Guile remains an extension language, no argument here.

However, describing it as “just” an extension language seems odd to me.
It doesn’t take into account what many have been doing with Guile, and
it doesn’t match the efforts that have gone into Guile since 2.0.

I don’t find embeddability to be that much of a salient feature.  After
all, CPython, Script-Fu, Lua, ECL, GJS, etc. all fit into that category.

Other adjectives I proposed (fast, functional) don’t quite apply to
these, though.

In what ways could it become “better” for this use case?

Personally, I encourage people to write more Scheme and less C, there
are lots of good reasons for that.  As a corollary, I encourage moving
from “embedding” Guile (linking your C/C++ program against libguile) to
“extending” Guile (having your main program written in Guile Scheme and
calling out to C/C++ bits as needed).  That’s been my position since the
2.0 days.
