Pattern matching in concatenative programming languages
... The idea of pattern matching is that, to see the contents of an object, the same syntax can be used as in creating the object, only on the left hand side of a binding rather than the right. This makes it very easy to write declarative code which manipulates functional data structures. In many functi ...
