Hmm. Well, the error your getting typically is the error you get when you're
missing an import, and I did a quick grep of phobos and saw that groupBy was
in std.range, which is why I told you to import std.range. Looking at
groupBy more closely now, it's part of SortedRange rather than being a free
function, and it doesn't take a predicate. So, I don't know why the Rosetta
code example is doing what it's doing. It doesn't match anything that's
currently in Phobos.
