No. It's like auto. The type is inferred. It's all statically typed and
strongly typed. It's not like it figures out the type at runtime or anything
like that. It's all done at compile time. It's just like C++11's auto. It
makes refactoring code a lot easier, and it makes generic code a _lot_ easier
to write. Without auto, std.algorithm would pretty much be impossible (you
_could_ do it, but it would be so disgusting that no one would want to use it,
because all of those compound range types get truly hideous if you actually
look at the types themselves - voldemort types have reduced that problem, but
they'd be impossible without auto anyway). It's up to you whether you want to
put types explicitly or use let them be inferred with auto or in foreach
loops, but it's more or less common practice at this point to use type
inferrence very heavily and to avoid using types explicitly except when you
need to.
