- Perform array (vector) operations and store the result in
res. Operand - types and operations are passed as template arguments in Reverse Polish
- Notation (RPN).
- Operands can be slices or scalar types. The element types of all
- slices and all scalar types must be implicitly convertible to
T. - Operations are encoded as strings, e.g. `"+"`, `"%"`, `"="`. Unary
- operations are prefixed with "u", e.g.
"u-", "u~". Only the last - operation can and must be an assignment (`"="`) or op-assignment (
"op="). - All slice operands must have the same length as the result slice. *
