   I'm writing a Shunting Yard interpreter for the CSS calc() function.

   Was thinking of implementing this in Haskell Stylist, but in certain cases where it is most useful I need to defer the arithmetic until after a couple layout passes... So it is also landing in CatTrap!

     A calc() interpreter has been drafted in CatTrap! Now I just need to write some unittests... I need to set a testrunner up...

     And I'll check what I wrote against the W3C specs.

     I even exposed some trigonometry, since it was on the MDN reference!

     Hmmm, I don't think I'll bother typechecking calc() formulas in CatTrap, I'll just let the rare poorly-written formula give weird results...

     If I'm not implementing any formal concept of CSS property types...
