Tentatively so. We still have to figure out how to generate the right
set of warnings, and the right conditions for suppressing those
warnings, since we don't want to undermine the invariant that "if a
program compiles with no (suppressed or not) raw or unchecked warnings,
then the casts inserted by the compiler will not fail."
As an alternative to doing it in the language, we will also consider
instead providing pre-peeled library methods like:
<any T> T newArray(int)

The current functionality continues with the erasure plan. However, I
wouldn't mind doing better!
