x_and_d: Generating elements for the first Weyl algebra

In RobinHankin/weyl: The Weyl Algebra

Generating elements for the first Weyl algebra

Description

Variables x and d correspond to operator x and \partial_x; they are provided for convenience. These elements generate the one-dimensional Weyl algebra.

Note that a similar system for multivariate Weyl algebras is not desirable. We might want to consider the Weyl algebra generated by \left\lbrace x,y,z,\partial_x,\partial_y,\partial_z\right\rbrace and correspondingly define R variables x,y,z,dx,dy,dz. But then variable x is ambiguous: is it a member of the first Weyl algebra or the third?
