Would it be more natural to have the following interface for interpolation:

  V.interpolate(v, w);

corresponding to w = pi_h(v).

?

This interpolates v into the function space and sets the coefficients
for w. This function can then detect whether or not v and w are on the
same mesh and choose the appropriate way to do interpolation.

We can also have a special case like

 V.interpolate(v);

which will take v and replace it by its interpolation.
