Given the `POINTER` type, consequent support for type-casting
pointers, and dynamic memory allocation, it's hard to understand
how VSI Pascal can be considered meaningfully memory safe in the
way that Rust or a managed language is.

I suspect that there is a lot of business code floating around
in memory-unsafe languages (MACRO-32, Pascal, maybe COBOL if
used in some odd ways) etc.  Not to mention FFI calls from safe
languages into unsafe code.

Rust on VMS would be cool.  Getting the compiler to generate
code that would load and run probably wouldn't be _that_ much of
a lift; a much bigger challenge would be getting the standard
library ported.  A Tokio executor for async code built on VMS
primitives would be cool; I suspect it's a pretty good fit.
