then that was a bug (probably a forgotten \protect

ah, in context \protect does something like \makeatletter in latex (only in 
context ! and ? are also used for protection purposes)

[afaik in latex there is a \protect that has to do with preventing 
expansion in toc entries; context does not need this since normally toc 
entries are not expand them at all; in context expansion only can be 
problematic in tests, which is why some commands are defined with 
\unexpanded\def, which actually in etex is equivalent to \protected  \def, 
which clashes with my own \protected, and (lucky me) \unexpanded is also an 
etex primitive with a complete different meaning; lesson: don't confuse 
\protect with latex \protect and don't mix up \unexpanded with etex's 
\protected]

anyhow, not something for users to bother about
