I disagree with being able to assign to the global defaultLocale. This
is going to cause endless problems. Just one is that any function that
uses locale can no longer be pure. defaultLocale should be immutable.
Any function that is locale aware should be parameterized with a
locale parameter. (Not only is that better design, it self-documents
the dependency.)
I don't understand this. That means there's no more default locale.
Here's what I had in mind:
class Locale { ... }
// function parameterized with an optional locale
void foo(Data d, Locale loc = null);
So there's no more default locale. If you pass in null, that's the
default locale.
That's fine, I was thrown off by your reference to a "global reference".
