- your definition of fromInteger will behave strangely with the elementwise extended operations, like (+). 1 + [[1,2],[3,4]] will become [[2,2],[3,5]] rather than [[2,3],[4,5]]. Array languages supporting this kind of overloading invariably have the second form of semantics.
Don't call an array a matrix. If is named matrix, it should have matrix multiplication, addition, and they should obey the expected laws.
But you still have the problem with the overloading of constants in your proposal. If you write 17 + a, where a is a matrix, what do people in general expect it to be? Björn Lisper
