FPC values backwards compatibility. As such a mode won't be changed in 
such a way that existing code suddenly no longer compiles without good 
reason.

Also as I wrote to Michael, the use of writable consts is as static, 
scoped variables if one doesn't want to resort to OOP (and for simple 
functions that might indeed be overkill).
