Unlambda is a minimal, "nearly pure" functional programming language invented by David Madore. It is based on combinatory logic, a version of the lambda calculus that omits the lambda operator. It relies mainly on two built-in functions (s and k) and an apply operator (written `, the backquote character). Read more on Wikipedia...


Example from Riju:
`. `.!`.d`.l`.r`.o`.w`. `.,`.o`.l`.l`.e`.Hi
Example from hello-world:
`r```````````.H.e.l.l.o. .w.o.r.l.di
# Hello World in unlambda `r```````````.H.e.l.l.o. .w.o.r.l.di
