Klong is a language based on K (probably K3) which removes K's syntactic ambiguity and much of its overloading by using more digraphs (primitive functions and operators composed of two characters) to separate extra meanings. The removal of syntactic ambiguity means Klong has a context-free grammar.
KlongPy
KlongPy is an independent, compatible implementation of Klong in NumPy. It can be closely integrated with Python due to its use of NumPy arrays, and can be run on the GPU using CuPy in place of standard NumPy.
Primitives
Klong documentation refers to primitive functions ("verbs" in K) as "operators".
