I'm only in partial agreement.  In my line of work, most of the code I write
deals with matrices whose sizes are known at compile time.  Of course, I
also deal with matrices whose size is not known until run time.  One of the
matrix libraries out there, MTL (IIRC), handles both situations with a
single class.  When COLS or ROWS is zero, the size is run-time specifiable.
I haven't seen the grid class yet, so I don't know if this is compatible
with what you have already, but you could do something along the following
lines:

grid<T,5,7> g;	// Compile-time 5x7 grid
gridT> g(5,7);	// Run-time specified 5x7 grid

Just an idea.
