`each`

Evaluates a body once for each value in a parser container.

each(container,value,body) traverses a Vector, Matrix, ValuesSet, Collection, or Dictionary and binds each visited value to the supplied local variable while the body runs.

Matrices are traversed in row-major order. The iteration variable is local to each body evaluation.
