Problem with \blackboard{} command

Hi together,

I've experienced a problem with \blackboard{} command. Please paste the
following code and compile it (I have newest CTX beta version (updating
daily)):

------------------------------------------------------------
\starttext

Variation 1:
$\forall n \in \blackboard{Z} \neq 0$: should be $0$

Variation 2:
$\forall n \in \integers \neq 0$: is $0$

\stoptext
------------------------------------------------------------

When the first variation is used, CTX seems to convert every folowing
letter into blackboard characters within the rest of the math environment
no matter where \blackboard brackets are placed.
Only when the second variation with \integers is used, CTX propely converts
every following letter. But imagine you need blackboard G for some reason
for example. Then the same bug will appear. I hope this can be fixed easily.


Greetings, Seba

The \blackboard command changes the math alphabet and is used like a 
normal font switch, to limit its scope you have to use it in this form:

     {\blackboard Z}
