For other uses, see QU (disambiguation).
Qu is an open-source computer programming language written in C by Marc Krisnanto. It comparable to Python, Ruby, Perl and many others.
The language is semi-dynamic, and optionally strongly typed, with full object orientation. All variables in the language are first class objects.
The design and implementation focuses on compactness and speed, using the GNU Lightning Just In Time compiler (JIT).
