Thanks for the kind words!

This can get you started:

Strings (and arrays) being length/ptr is a freaking enormous win, in simplicity, performance, and overflow bug elimination.

One of D's secret features is that string literals still have a 0 appended to them, even though the length of the string does not include the 0. This makes it super slick to call C functions, like printf, using a string literal for the format string.

I'm baffled why C spends its energy doing things like normalized Unicode identifiers (an abomination) instead of something incredibly useful like length/ptr arrays.
