BUILT_IN_FRONTEND - how did this work?


Hello,

It seems that there once was support for builtin functions defined by
a front end. This is still a useful idea (see e.g. PR24777) but it
looks like there are no frontend built-in functions anymore. At least,
a grep for BUILT_IN_FRONTEND gives no meaningful results. There's a
hint that it may have worked, long ago, in ChangeLog-2000. But there
is no documentation whatsoever about how BUILT_IN_FRONTEND is supposed
to work.

Does anyone know how BUILT_IN_FRONTEND should work, what one has to do
to define a front-end built-in function? Examples? Any idea if there
ever was a front end that used this feature?

Ciao!
Steven
