:)  Trust me with the calc situation even worse:

For example layout like (four inline blocks: f1,f2,f3,f4):
|<--25%%-->|<--fixed:100px-->|<--50%%--->|<--25%%-->|
(Again %% means here percentage from free space = contentWidth-100px)

Following your logic this should be represented by formula like this:
f1{
   width:calc(25%-33px);
}
f3{
  width:calc(50%-33px);
}
f4{
  width:calc(25%-33px);
}
Right?

Algorithm which will force sutuations like: 100px = 33px+33px+33px
is extremely bad.  Moreover:
If you have three calculated values dependant from fourth you will NEVER
reach what you want.
Discrete math.

Beg my pardon, is it clear what I mean here?

One more problem with calc():
Formulas in styles will force designer to put dependant values in different
formulas. See example above.

No human will be able to handle such calculations with any *real* layout
where he/she should follow and recalculate each time depandencies like this.
Only software. Personaly I am happy about that as designers will be forced
to buy my blocknote.net but I don't think this is an intention of W3C.
