incompatibility mp-tool and metaobj

[Eckhart Guthöhrlein]

I tried to embed a picture created with the metaobj package (btw: a 
terrific one!) in a ConTeXt document. This results into the following 
MetaPost error message.

(D:\mytexmf\metapost\metaobj\metaobj.mp
******* metaobj 0.8 (c) D. Roegel (2001/06/14) *******
! Missing argument to exp.
<to be read again>
                    @#
l.1552 vardef resetObj.exp@#
                             =
?

I think this is a conflict between this definition and the definition of 
exp in mp-tool.mp.

Is the exp in resetObj a private method (in which case it can be renamed)
or a public one?

It is a public one. The following code is sufficient to reproduce the error.

\startreusableMPgraphic{test}
    input metaobj;
%   draw fullcircle scaled 1cm;
\stopreusableMPgraphic
\starttext
    \reuseMPgraphic{test}
\stoptext

Well, it is for power users, it is experimental (that's why I appended
a ``exp'') and it is documented in the manual...

(This reminds me of a discussion we had about namespaces... :-))

I think I don't have the choice and will have to change the name
of that definition and of a few more that have also that extension.
Try to replace all ".exp" with ".expl" in metaobj.mp. It should work
better.

I will try to upload a patched version next week.

i was more referring to public as 'meant for the user', private methods are
less sensitive to a low level change, anyway, toe sooner we sort out
conflicts, the better

btw, in the latest update of context there are a couple of more macros (not
yet documented), like macros for smoothing corneres, removing redundant
points, removing uggly things etc. [i needed them for complex backgrounds]
i hope to describe them soon,
