Question

What does Mirah language offer over JRuby,Groovy and Scala?

Answer 1

Unlike full-featured languages, which come with their own libraries, Mirrah is more like a different "frontend" to the Java libraries.

Mirrah code does not depend on it's own environment (except the Mirrah compiler at compile time).

That's the main benefit: A different syntax for Java.
