The behaviour must be fixed for __traits(compiles,...), but not necessarily for
typeof.

alias typeof(Length.init*Length.init)         Area;
alias typeof(Length.init*Area.init)         Volume;
alias typeof(Mass.init/Volume.init)         Density;
...

or even

alias typeof(meter*meter)                       Area;
alias typeof(meter*meter*meter)                 Volume;
alias typeof(kilogram/(meter*meter*meter))      Density;
