At the beginning you have to think a bit about it, but you quickly learn it, and you find it's the best way to design it :-)
Several languages use this same convention.

It allows you to split an array in two parts with very little troubles:
s[0 .. $] == s[0 .. n] ~ s[n .. $]

It's especially good when all the language uses this idea, for example, in D2, this loops ten times, and x never becomes 10:
foreach (x; 0 .. 10) {...}
