Here's a little quick and dirty square matirx multiply I've written. 
Ok. I know
this leaves a lot to be desired on the quality front, but I'm not in a 
position to
rewrite the whole system here!
The lambda function argument to accumulate is clearly not right, but how I
write something that implements the intention here?
Iter( 0 ), Iter( BLOCK_SIZE ), 0, l[ y ][ _1 ] * r[ _1 ][ x ] );
I think you need

var(l)[y][_1] * var(r)[_1][x]

(Remember that operator[] can only be defined as a member)
