trouble with math arrows

trouble with math arrows

[Jesse Alama]

Something goes wrong with this simple example:

<--- snip --->
\definemathoverarrow  [overrightarrow]      [\rightarrowfill]
\def\Ray#1{\overrightarrow{#1}}
\starttext
Hello world! $\Ray{ABC}$.
\stoptext
<--- snip --->

It leads to:

! Missing $ inserted.
<inserted text> 
                $
<to be read again> 
                   \displaystyle 
\dodohandlemathoverarrow ...{\ialign {##\crcr #2#3
                                                  \crcr \noalign {\kern #1\n...

\mathpalette ...>\mathchoice {#1\displaystyle {#2}
                                                  }{#1\textstyle {#2}}{#1\sc...
l.6 Hello world! $\Ray{ABC}
                           $.
? 
! Emergency stop.
<inserted text> 
                $
<to be read again> 
                   \displaystyle 
\dodohandlemathoverarrow ...{\ialign {##\crcr #2#3
                                                  \crcr \noalign {\kern #1\n...

\mathpalette ...>\mathchoice {#1\displaystyle {#2}
                                                  }{#1\textstyle {#2}}{#1\sc...
l.6 Hello world! $\Ray{ABC}
                           $.

(This is done with a live pdftex on the garden.)  Any ideas?

Thanks,

Jesse

\definematharrow needs three arguments, the second is bunch 
of digits representing distance corrections. See the My Way on arrows and
