> Maybe thee's still space for a modern language for numerical computation whose efficiency is not encumbered by the need to support strings, dictionaries, multiple dispatch and the like? I don't think so: I don't know of any scientific code that doesn't have to interact with its environment, if only to import/export data, and for that, strings at the very least are necessary. Multiple dispatch is the same thing for me; either it or another form of polymorphism will be very quickly asked for by the users of a scientific language, as no one wants to write dozens of time the same functions for different types, and the HPC community loves its programs to go fast, so they need/want to be able to chose their types.
