Flux is a modern systems programming language designed to be readable and writable, without sacrificing expressiveness or power.

It allows unmatched capability in data manipulation as well as novel unique features found in no other language.

Opt-in ownership with no borrow checker, an extremely lean runtime, beautifully simple templates with no SFINAE, and everything zero-initialized by default.

Write with the power of C++ and the terseness of Python.
