"Katahdin is a programming language where you can define new language
constructs such as expressions and statements as easily as new types or
functions. For example, you could define a new operator, a new type of
loop, implement a syntax from another language that you like. After
defining a new construct you can use it on the next line in the same
file, so there is no need to recompile each time you want to add a new
construct. Katahdin is powerful enough that you can define an entire
existing language, or design a new language from scratch, making
Katahdin a universal language interpreter."

Not sure how novel this is though, you could say the same about many
languages I'm sure.
