I was looking through the standard library for a good way to split a range into several ranges based on value changes in the stream:

AAAAAAABBBBBB
would be split on the AB transition into:
AAAAAAA BBBBBB

I just couldn't figure out an elegant way to do it? Any ideas?

Like this?

´´´
void main()
{
    import std;
    "AAAAAAABBBBBB"
        .chunkBy!((a,b) => a == b)
        .writeln;
}
´´´

Just like that.
