Research direction

Start by reading the ScalarOperand trait and the existing impl_scalar_lhs_op macro referenced in the issue. Determine the public macro interface needed for a user-defined scalar type, then verify that it supports the documented arithmetic operations on both operand sides.

Written by the indexing model from the issue text.

Description

enhancement

Currently, to define a new scalar type usable in arithmetic operations involving scalar operands, the user needs to do the following:

  • Implement ScalarOperand for the scalar type so that it works as a right-side operand.

  • Add implementations for the scalar type on the left side. (In other words, copy the impl_scalar_lhs_op macro and apply it to the scalar type.)

It would be nice to provide a macro to make this easier.
