[dev-context] new mp feature

[Mojca Miklavec]

Question, questions and questions again ...

The question from yestarday wasn't a serious one. But this one might
get closer. After I've rewritten the context.trm to try the new
\sometxt out, I struggled against the following problem:

\startMPcode
picture p;

vardef rotateme(expr m) =
	(m rotated 90)
enddef;

% this works
p := \sometxt{sin (x)};
draw rotateme(p);

% this doesn't
draw rotateme( \sometxt{sin (x)} );
\stopMPcode

Is handling the second situation too complext for the existing
mechanism? The solution on "my side" is trivial - I can split the
behaviour in the gnuplot module to work in two steps instead in a
single one, but perhaps this can be easility fixed as well.
