The problem with that is once you start to do conversions, things quicky
go south, as conversions can depend on runtime variables, and people get
really weird bugs when their expressions are not evaluated in the same
time always.
In static context, like with proposed patch, nobody has expectations so
saying "it all happens compile-time, runtime settings do not apply" is
fine. But when you already have running code that works certain way,
changing it may be dangerous.
