'int' is enough for 'length' to migrate code from x86 to x64

I recently explained to you that explicit casts are easily avoided using 
`import std.conv: signed, unsigned;`.

D compilers badly need a way to detect bug-prone sign mixing. It is no 
exaggeration to say D is worse than C compilers in this regard. Usually 
we discuss how to compete with modern languages; here we are not even 
keeping up with C.

It's disappointing this issue was pre-approved last year, but now 
neither you nor even Andrei seem particularly cognizant of the need to 
resolve it. If you belittle the problem, you discourage others from 
trying to solve it.
