While re-writes are certainly the simplest way to explain it, using them in the
compiler often leads to complications, especially with error messages referring
to the re-written code instead of the original.

For this case, and similar cases, the compiler can simply type the array
literal as a static array, because it knows that == can't escape any
references.  It already does something like this for indexing array literals.
