It's not a recent change, but there has been a recent thread about
switching to variableNames (amongst other things):
> This implies that the traditional i,j,k loop indices should now be spelled I,J,K. Is is worth making an exception for single character variables where the meaning is implicit from the context?
I certainly would, and it seems most people agree. "int i " seems to
be about 4x as common as "int I ".
> As an edge case, should function pointers be leading lower case (as they're functions) or leading upper case (as they're variables)?
I believe they're mostly upper-case right now (though pretty rare). I
think named lambda helpers vary more but still favour upper-case.
