Crules is a dynamic programming language that takes influences from Python, Perl, and Haskell. The main motivation for this language was the concept or design of a new paradigm or feature called "rules". A rule is a potential entry point which has dependencies rather than parameters. Any rule can be overridden to have different or no dependencies. Since the language itself can decide on the best course of actions for an operation, dependencies become preconditions for execution. It also features lazy evaluation, object orientation, variadic and anonymous-parameter functions, and reflection. These features help make the language truly dynamic.
Hybris (hybrid scripting language) is a dynamic scripting programming language created to help developers to automate everyday procedures in a easy and fast way. Although is a high level language, Hybris supports dynamic library linking, native C function calls, and a lot of other low level functionality.
