Rubiq will try to be as close as possible to a real Lisp, while still retaining interoperability with both Ruby and Java. The Lisp syntax will be more influenced by Common Lisp than Scheme. A few features that will be very important is correct handling of lambdas as blocks, macros, read macros and an extension mechanism that will make Ruby-Lisp interop work correctly from both sides. The core of the system will have one layer or special forms and pure Lisp methods, which then translates directly into a JRuby AST. This translation makes it possible to use features of the AST that regular Ruby code can't.
