Limbo (programming language)

Limbo is a programming language for writing distributed systems, created at Bell Labs by Sean Dorward, Phil Winterbottom and Rob Pike, and first appearing in 1995. It is the language used to write applications for the Inferno operating system. The Limbo compiler produces architecture-independent object code, which the Dis virtual machine either interprets or compiles just before running for better performance, so that every Limbo application is completely portable across Inferno platforms. Its concurrency model, built around communicating processes and channels, reflects Inferno's design for building networked and distributed systems that run unchanged across many kinds of hardware.
