> I'm sorry to bring the bike shed discussion here, but I would like to consider ** exponentiation. The reason is that writing ^^ for people with keyboards with "dead keys" (to write accents for example) is very hard, because you have to write "^" like this: shift+6 space (3 keystrokes), or even worse (unless you use Emacs ;): shift+alt_gr+6.

If remeber it correctly, you don't have to type space in this case, just hit shift+6 two times. Yes, the first hit will be the dead key hit, but the second will yield ^^ at once.

Not with my keyboard configuration, I can hit Shift+6 twice, but that yields only one ^, so I have to press Shift+6 four times to get ^^ :)

I have to do that too, but only on Linux.  On Windows, it only takes two presses.  This is using a Norwegian keyboard, where the caret is on a different key, but you still have to hold down the shift key.

Maybe it's time to upgrade to Windows?

It's strange, I tried english-international and french layouts - they work as I described.

Just wanted to write: Thanks!

I have about 10 classes with already deffinied opPow just waiting to this for years.


About Walters question about opPowAssgn, i have few place where i'm for. example squering in place,  or  (in. for computing exponent of interval matrix), this isn't actually inplace, but makes code more readble, other i example in my libraries i see units library, where i see something like this:

    Self opPowAssign(int b) {
        if (b >= 0) {
            nom = pow(cast(int)nom, b);
            denom = pow(cast(int)denom, b);
        } else {
            auto newnom = pow(cast(int)denom, -b);
            denom = pow(cast(int)nom, -b);
            nom = newnom;
        }
        return this;
    }

Clearly first can use opPowAssign, of course in such simple example compiler should be detect that x = x ^^ y, for simple types can be done in place. And this opPowAssign is used in few places also.

Or clearly like this:

    Self opPowAssign(int b) {
        nom ^^= b;
        denom  ^^= b;
        if (b < 0) {
            swap(nom, denom);
        }
        return this;
    }


I have also few places with something like:

  new_step = pow(previous_step, f(x))

  it can be changed to: step ^^= f(x).

and new_step is not nacassarly float or double, it can be slightly more complex structure like interval vector (and exponentation of it can be done in-place).


I also think that sometimes pepole will have not enaugh operators, and for the sake of consistency it is good to have opPowAssign. :) Not nacassarly good for clearity of code if it will use ALL opXAssign for very diferent things.

It is also usefull to have opPowAssign for vector operations:

 float a[],. b[];
  a[] ^^= 2;
  a[] ^^= b[];

It should be easier to compiler to generate better code, than from this:
  a[] = a[] ^^ 2;
  a[] = a[] ^^ b[];

BTW is ^^ supported as operator in array operations? IT definietly SHOULD.
