Rewrite certainly not, that will be stupid, but building binding when needed is certainly a safe path in the long run. > - (vicious) There's also a company that is pursuing a subset of Ada, > with annotations.

Why modify the GNAT runtime. This is a library right ? Ada with tasks, protected object is certainly in a good position to propose something. Maybe starting with AWS is a good idea...
