\implies doesn't work
! Undefined control sequence. 
<recently read> \implies
l.11 $\implies 
             $
?
*I* think \Rightarrow should be exchanged for \implies, as \implies generates a slightly longer arrow.

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.

Indeed, it seems to be broken in mkiv
\rightarrow
\to
\leftarrow
...

However, \leftrightarrow works.

So, currently, it is hard to typeset limits under mkiv!

It seems that \rightarrow is missing.  The command exists, in the sense

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
