Pardon my being scatterbrained (and there not being an "edit 
post" function) - you're referring to phobos not considering 
char[] and wchar[] to have random access? The reason they are not 
considered to have random access is because they are auto-decoded 
by other functions that handle them, and the auto-decoding makes 
random access inefficient. Not because shuffleRandom itself 
auto-decodes them.
