\mathematics

Hi.

When writing math I like avoiding $ whenever possible by defining my math
operators with \mathematics, e.g.
\def\grp{\mathematics{G}}.
So far I was using this like I use \EnsureMath in LaTeX, but now I'm running
into problems in MPgraphics:
Texexec compiles the following file fine until I add the paragraph called
"Math in Math in MP". There it seems to somehow
choke on too many $ and \relax.

Is there a better way to do such definitions?

Thanks,
Boris.

PS: There's already a problem in the second to last paragraph where the G is
not set in math mode any more.


The example file:

\def\grp{\mathematics{G}}
\starttext
Test.

Running text:

A group \grp

Math:

$\grp$

$\grp_{\grp}$

Text in MP:

\startusableMPgraphic{groupone}
label(textext("\grp"),origin) ;
\stopusableMPgraphic

\useMPgraphic{groupone}

Math in MP:

\startusableMPgraphic{grouptwo}
label(textext("\mathematics{\grp}"),origin) ;
\stopusableMPgraphic

\useMPgraphic{grouptwo}

Math in Math in MP:

\startusableMPgraphic{groupthree}
label(textext("\mathematics{\grp_{\grp}}"),origin) ;
\stopusableMPgraphic

\useMPgraphic{groupthree}

\stoptext
