Systems languages are already going to be somewhat close to the metal.
They're an alternative to rewriting your code completely for every
platform you're on. If you have to guard a few small sections with
configure-time checks, that's still saved you the work of writing all
the rest of your code twice.

With applications languages, as earlier mentioned, none of this should
be necessary. Sacrifice the performance and have arbitrary-precision
integers, Unicode strings, garbage collection, and first-class
lists/functions/mappings etc. This is only about lower-level
