Scalar-matrix product

>>> 5 *!! V2 (V2 1 2) (V2 3 4)
V2 (V2 5 10) (V2 15 20)

use :: Monad m => b -> VarT m a (Event x) -> VarT m a (Event b)

Populates a varying Event with a value. This is meant to be used with the various on... event triggers. For example, use 1 onTrue produces values of Event 1 when the input value is True.

Matrix-scalar product

>>> V2 (V2 1 2) (V2 3 4) !!* 5
