Curly: multi, but with balanced if-else statements

[bathos]

I came here because I ran into the problem at #2366, and it's awesome to see it was just fixed yesterday! I had two other concerns related to brace style as well, both of which are feature requests rather than bug reports.

The first I discovered was already detailed at #1806.

The other I didn't find described yet. I'm curious whether a style option extending 'multi' for curly might be considered, for handling if/else blocks nicely. In my experience those of us who favor multi will nonetheless wish to balance if/else blocks when one or the other is multi-statement. That is, if either 'if' or 'else' is a multi-statement block, the other should use braces as well, or else you end up with rather awkward results.

So the legal forms would be, as with multi:

if (condition)
    statement();
else
    statement();

and of course:

if (condition) {
    statement();
    statement();
}  else {
    statement();
    statement();
}

but also, this, which is considered an error when using 'multi':

if (condition) {
    statement();
    statement();
} else {
    statement();
}

instead of the form which is currently considered valid (and which I've rarely seen used in practice, for reasons that seem apparent):

if (condition) {
    statement();
    statement();
} else
    statement();

We're getting a bit into fuzzy areas here. I think what you're asking for is that if one branch of the if statement has multiple statements then all branches must use curlies, is that correct?

I'd call this "multi a consistent".

[bathos]

Yes, that's correct.

Interesting option, I'd like to use it. Working on it.

I was gonna propose this actually. We need this at work too :) 👍

FYI: With non-allman style braces, I agree. However, with allman style braces, inconsistent use of braces looks quite natural (to me and my colleagues at least):

if (foo)
{
    doSomething();
    doSomethingElse();
}
else
    doBar();
