This is because although static_cast is equivalent to an old-style cast for primitive numeric types, even experienced C++ programmers will think it does something subtly different for at least a moment and then have to remind themselves it doesn’t. Smoothing away all such tiny speedbumps is the difference between code which can merely be understood and code which is pleasant to read.
