I've just had a look at that; it doesn't seem to provide much of a
basis for an actual tool along the lines of r.mapcalc.

The first thing to decide is the structure of the processing pipeline. 
E.g. for r.mapcalc, the expression is evaluated for each row of the
result. An N-parameter function takes N buffers as input, one row of
each input raster, and stores the resulting output row in the output
buffer.

What would the processing model be for v.mapcalc? What would the
"values" be? Complete vector maps?
