There are some advantages to trailing return types (introduced in
C++11) particularly for function templates where the return type
depends on the argument types.

If C++ were being designed from scratch today, I suspect that they
would be the only syntax accepted, with the leading "auto" omitted.
Other than historical baggage, there's no good reason to have two
different syntax for return types.

Some have argued that we should use trailing return types
consistently in new code.  Others would argue that we shouldn't
use them in cases where they offer no specific advantages, simply
because they're unfamiliar.  I tend to fall into the latter camp,
but I can imagine changing my mind eventually.
