a couple more thoughts about this...

what namespace is your comma operator in? it could be placed in an extra
namespace which users can explicitly pull in if they prefer the super
compact (albeit controversial) syntax and then anybody else could stick
with a normal free function (like my swizzle(v, xy) above) which would be
in the normal qvm namespace
