Bug with command \to in captions

Bug with command \to in captions

[morgan.brassel]

Hi,

The simple example:

\starttext
\placefigure[][]{$x \to 0$}{My figure}
\stoptext

does not compile, whether it's on my installation or on the live interface.
It seems that there is a problem with using \to in captions... Or maybe I'm
missing something...

Morgan

ConTeXt use \to as part of an internal macro and is missinterpreted in this case
but you could use \rightarrow instead.

\starttext
\placefigure[][]{$x \rightarrow 0$}{My figure}
\stoptext

I thought that this bug had been removed almost a year ago, but it is 
still there.

Hans, how about defining another macro, \!!appendtokens ... \!!to ... and 
changing the internal usage to this macro. The macro \appendtokens ... \to 
... macro must stay (since it is present in many user docs). Would this 
get rid of this bug?

this was not an appendtoks but a \convertargument \to

i replaced most of these (plus \convertcommand) but i'm not sure that i 
didn't make mistakes so i uploaded an alpha ... feel free to diff the lot

(maybe taco can generate me a diff of the zip that we can check)
