Pascal is designed to be safe, like Rust is. Pascal was missing some things needed for systems programming but those were added in Pascal's sequel, Modula-2, whose sequel, Oberon, ended up being a very nice language.

It's too bad Modula-2 didn't come along earlier to compete with C. We could have avoided most of the security problems with C and C++ programs.

Instead, here we are, 50 years later, finally moving toward safe languages again. Took long enough.
