Ah, ok - that makes sense. For a simple
    rh(rh.totalDomain()) = T;
I dont need to specify the domain of T? I assumed a conforming domain gets
selected by the engine for the RHS...

Hmm - I compiled the pooma lib with optimizations (i.e. assertions off),
but my program with debugging and assertions not switched off - maybe the
exception in question is not raised within templated code. I'll try
re-building pooma with debugging information (but it gets slow as hell).

Thanx, Richard.
