Inconsistent array mathematics for enumerated arrays

[GriffonOak]

Context

Odin:    dev-2024-09-nightly:dd1f151
OS:      Windows 11 Home Basic (version: 23H2), build 22631.4169
CPU:     AMD Ryzen 5 5600X 6-Core Processor
RAM:     32691 MiB
Backend: LLVM 18.1.8

The following code demonstrates the problem:

package main
import "core:fmt"

Enum :: enum { P, Q }

EnumArray :: [Enum]int

main :: proc() {
    a: EnumArray = {.P = 2, .Q = 3}
    b: EnumArray = {.P = 4, .Q = 5}

    fmt.println(a + b)      // prints [.P = 6, .Q = 8]
    fmt.println(a * b)      // prints [.P = 8, .Q = 15]
    fmt.println(a + 2 * b)  // does not compile

    // Workaround using transmute:
    fmt.println(a + transmute(EnumArray) (transmute([len(Enum)]int) b * 2))
    // prints [.P = 10, .Q = 13]
}

Expected Behavior

Scalar multiplication should work with enumerated arrays of numeric types exactly as it does with normal arrays of numeric types.

Current Behavior

Enumerated arrays support addition and multiplication between each other, but not multiplication by scalars.
