This is certainly an interesting extension, but it sounds like it will need updates to the programming language itself (the syntax, not just the compiler) to benefit from it, mainly in regards to dynamically allocated buffers.

On the other hand, languages like Java that already do array bounds checking, just need a JVM change to offload that to the CPU.
