It would actually be of substantial benefit to readability if you *could*
overload operators for numeric, vector, and matrix-like types. In
particular, I'd strongly prefer if SIMD types, if added, *did* use
overloaded operators similarly to the BigInt proposal - it's honestly
ridiculous why people use SIMD intrinsics for things that equate to vector
addition (in the math sense).
In particular, here's a couple examples of what I mean from a math
standpoint:
Vector (3D point) addition:
<a, b, c> + <x, y, z> = <a+x, b+y, c+z>
Matrix multiplication (2D):
[a, b] [x, y]
[c, d] × [z, w] =
[ax+bz, ax+bw]
[cx+dz, cx+dw]
Complex number division:
(a + bi) ÷ (c + di) =
(ac+bd) + i(bc - ad)
--------------------------------
c²+d²
Set symmetric difference (i.e. exclusive or):
{1, 2, 3} ⊕ {1, 2, 4} = {3, 4}
I'd strongly prefer an operator variant over any method version, because it
matches the math notation much better. You shouldn't actually need to learn
some naming idiom just to add two things.
