For my own consistency, I would like
/ A \* 100
to equal
A / 100.

I am not sure what you are asking for here, but it may not be possible, as `/` is parsed as a binary operator.

There’s a binary and a unary form of `-` already, but I don’t know if it’d be worth the change or break something to introduce a unary `/`.

Even then, the semantics would probably not match the required one.
Since some form of AST transformation would be needed anyway, something like
```julia
using MacroTools
macro /(expr)
@capture(expr, A_ * B_)
:($A / $B)
end
julia> @/ 1 * 100
0.01
```
could be a starting point.

I don’t understand what you mean, for unary minus, we have
```julia
-a + b == b - a
```
so maybe you meant
```julia
/a * b == b / a
```
I guess you can use `1/a` or `inv(a)`

Oh I’m sorry, I read that as `\ A * 100 should equal 100 \ A`. Now I don’t know if this is what @vaeli intended, or if he really means it should be `\ A * 100 == A \ 100`, which looks kinda odd to me.
