Are div and / meant to be the same?

Thanks for your prolific and amazing contributions.

I don't understand the following type mismatch when using / vs div:

import vmath
let a = uvec2(10, 10)
a/2 # type mismatch
a.div(2) # uvec2(5,5) == type GVec2[system.uint32]

Sorry I couldn't work it out by myself, they both seem to use genOp.

Interestingly I get the same problem the other way around with vec2:

import vmath
let b = vec2(0.3, 1)
b/0.3 # vec2(1.0, 3.33...) == type GVec2[system.float32]
b.div(0.3) # type mismatch

I don't see a problem here. I think the confusion comes from the fast that a.div(2) returns some thing and needs to be discarded or saved. Same from the b/0.3 case. Also I would write that as a div 2 as that is more common as div is acting like an integer version of the / operator.

This is the test I ended up using that show the correct and expected behavior:

  block:
    let a = uvec2(10, 10)
    var b: UVec2
    when compiles(b = a / 2): doAssert false # type mismatch
    b = a div 2

  block:
    let a = vec2(10, 10)
    var b: Vec2
    b = a / 2
    when compiles(b = a div 2): doAssert false # type mismatch

Feel free to reopen if I missed some thing.

Thanks for feedback, maybe my type-sloppiness from years of python and clojure is to blame :)
