Self-hosting

Standard ML is a self-hosting language: its compiler is written in Standard ML itself. Self-hosting means the compiler can compile its own source code, which is a milestone in a language's maturity. New versions of the compiler are built using an older version of the same compiler, a process called bootstrapping.

Self-hosting also acts as a practical stress test: if a language can compile its own compiler, most core language features have been validated in a complex, real-world workload. See what is compiler bootstrapping for a full explanation.
