Why do some people prefer “T const&” over “const T&”?

Question

So, I realize that const T& and T const& are identical and both mean a reference to a const T. In both cases, the reference is also constan

Answer 1

If the const and & get far apart, as in

krog::FlamBlott>
speckleFlams( const krog::Floonage & floon, const std::map>> & obsmap);

krog::FlamFinagleReport
finagleFlams( const krog::Floonage & floon, std::map>> & obsmap)

... then it becomes easy to miss that the first 'obsmap' is a const reference and the second is not.
