We foresee having an infinite number of locals per function, but we plan to pre-color them so that locals whose lifetimes don't interfere can be merged. We can get clever and do this...

Hello all, WebAssembly [0] its a new virtual ISA being designed to efficiently run compiled code in web browsers and other things, starting with C/C++, and eventually many other languages [1]. WebAssembly distinguishes itself from other virtual ISAs with optimizations to reduce download size and decode time, strong portability and predictability invariants (for example, the base has no undefined
