Implemented in a systems programming language has everything security related that C lacks.

> Bounds checking, explicit unsafe blocks, proper strings, explicit type conversions, proper enumerations, checked arithmetic.

Language and OS features.

Recent hardware versions use Xeons.

Again, just features missing from C, and available in other languages.

Another notable feature, it did not make use of any Assembly, in 1961, because all CPU features are exposed as compiler intrinsics.
