I like this idea to exchange the meaning of const and invariant *VERY* 
much. Personally I prefer "invariant" to "readonly", but this is negligible.

The very nice side effect of this change would be, that we could kick 
the recent enum changes (which practically nobody likes *eg*), in favor 
to the much more intuitive and backward compatible "const PI = 3.14" 
form for manifest constants.
