Dear Hans,
maybe my request comes a bit late, but nevertheless - how difficult is
it to fix \longrightarrow in MKIV in Lucida font? (In MKII it works
fine.)
\setupbodyfont[lucida]
\starttext
$\longrightarrow$
\stoptext
The arrow has white space in the middle.
Thanks a lot,
Mojca

I assume that jointwo(...) function is used to create the longrightarrow and maybe that one doesn't get the spacing right.

This fixes the problem indeed: jointwo (main,characters,id,size,0x27F6,0x0002D,4,0x02192) (line 332 in math-vfu.lua). It seems that joinrel is hardcoded to the value 3 in many places apart from this particular one. Maybe you need to introduce a new lua variable somewhere inside function vfmath.alas(main,id,size)?

So, no complex defs are needed. Maybe there are more relevant variables.

This is exactly what I wanted to suggest (as it avoids complex situations with multiple definitions).
