The funny thing is they can be syntax-compatible too: in my libs there are sorted() and sort() (the first creates a new array and the second works in-place), they can be used like this:

string[] a2 = ["Liu", "Verylongword", "word", "average"];
a2.sort(&len!(string));

Result:
a2 == ["Liu", "word", "average", "Verylongword"]

Where len() is a refined function template that returns length of lazy/eager iterables, using the .length attribute where possible.

So a2.sort and a2.sort(...)/a2.sorted(...) don't clash.
