*sigh* That doesn't work. From the wikipedia article:
In traditional static compilation, method overriding can make escape
analysis impossible, as any called method might be overridden by a
version that allows a pointer to escape.
For example: Let's take a 3rd party pre-compiled library with class A
and function f(A a), neither of which have any escapes. Now create a
subclass of A, B, which does contain escapes. Does f(B) escape or not?
It also says that Java 6, a language compiled as I proposed D could be,
has escape analysis.
I don't think it's easy, but it's definitely possible.
Besides, this entire argument is moot if Walter doesn't want to do it...
