Hi Hans,
Testing your last night's beta,
LuaTeX, Version beta-0.40.1-2009050813 (Web2C 7.5.7)
ConTeXt ver: 2009.06.04 22:20 MKIV fmt: 2009.6.4 int: english/
english
I noticed that \longrightarrow is missing in mkiv, while everything is
correct in mkii.
Here is a minimal example:
%%% begin example
\starttext
Consider a continuous function $f : (0,1) \longrightarrow E$, where $E
$ is a Banach space, as above.
Consider a continuous function $f : (0,1) \rightarrow E$, where $E$ is
a Banach space, as above.
\stoptext
%%% end example
In mkiv nothing appears for \longrightarrow, although the typesetting
goes through.
Thanks for your attention: OK
