Yes, each "row" in the matrix needs its own object.  Every use of [] to 
access a property must have an object as its left operand.  Just as 
a.b.c requires a and b to convert to objec type, so a[i][j] requires a 
and a[i] to be objects, or convert to object type in useful (persistent) 
ways.

Don't get hung up on the [] syntax.  It's just a generalization of the . 
syntax.  For a.b, b must be a lexical identifier.  For any other 
property name, you can say a['@%$#b'], e.g.

/be

.
