It was to express the concept of an array in the linear-algebra sense, =20
rather than a generic container. Indeed, I shuddered slightly this =20
morning when I saw TridiagonalOperator's methods being applied to =20
generic containers :) I'm not sure that I like it.
Also, it allowed us to write things like operator*(Matrix,Array) which, =20
being specific for linear algebram I wouldn't add to std::vector's =20
interface.
