It seems that \rightarrow is missing. The command exists, in the sense
that its use doesn't lead to an error, but it doesn't lead to anything
in the output. Minimal example:
\starttext
$\rightarrow$
\stoptext

Hans,
What does the new arrow function in math-vfu.lua supposed to do?

it will be used instead of the macro based one (as luatex has native
support for such extenders now) but i had to wait till you fixed all the
other arrows that you added someplace

Indeed, it seems to be broken in mkiv
\rightarrow
\to
\leftarrow
...
However, \leftrightarrow works.
So, currently, it is hard to typeset limits under mkiv!

Hans, this has to do with the arrow function in math-vfu. Do you know why
this is failing?

I switched from MkIV to MkII today because of this gap in MkIV's math:
I need to submit a dissertation that has \rightarrow's in it. Let's
hope that this issue is resolved soon.

in math-vfu, patch:
--~ main.characters[unicode] = { horiz_variants = t }
main.characters[unicode].horiz_variants = t
and
[0x02190] = 0x20, -- leftarrow
[0x02192] = 0x21, -- rightarrow
--~ [0xFE190] = 0x20, -- leftarrow
--~ [0xFE192] = 0x21, -- rightarrow
and remake the format
luatex has native support for extensible arrows and since lm lacks them
we need to construct them

How do we "extend" these arrows? Traditionally, amstex uses \x...arrow
commands for extensible arrows, and \...arrow things are fixed.

Currently, \implies, \iff, and \impliedby are not mapped. We need a
cleaner model to map symbols with spaces.

\implies is usually defined as \;\Rightarrow\; so the size of the arrow
should be the same.
