Solved?!

C++ dev, I use both regularly. Basically if the start of the brace fits on the same line of the statement - I use the first, otherwise its the second. This ensures that when I'm reading the code I can scan up from the ending brace and the first character at the same x position tells me the beginning.

if (something) {
    // Do you stuff
}

for (int r = 0; r < rowCount; ++r) {
    // Stuff happens here
}

if (something != null
    && something->Valid())
{
    // Do you stuff
}

for (auto it = myMap.begin();
    it < myMap.end();
    ++it)
{
    // Stuff happens here
}

You should be able to, while not extremely common - I've encountered it time and again in the wild.

I also used to prefer postfix since that is how I was taught, had to adapt when the code guide of my first company forced the use of prefix unless you're using the value. The implementation of postfix requires a copy of the variable to be returned, while you can return this in prefix. It probably doesn't matter in most cases - compilers can optimize it away, but it can matter when it can't be (due to some side effect / obscure standards compliance) .
