Is this actually type safe, or type safe up until you include an untyped gem and the whole thing becomes indeterminate? Does the typing actually improve performance over straight jRuby? Can it handle method_missing and *_eval? Also why is it closed source? edit: sorry I didn't mean to sound aggressive. please interpret the stream of questions as extreme curiosity. |

The type system is roughly the same as in Java, and, as in Java, there are ways around the type system.

The compiler requires type annotations; you can't include an untyped gem! InfraRuby syntax is compatible with Ruby interpreters, so you can still use your code while you write type annotations for it.
> Does the typing actually improve performance over straight jRuby?
Yes. The compiler is written in Ruby, and uses JRuby to bootstrap. The performance of the compiled compiler compiling the compiler is about 7x JRuby.

No. The subset of Ruby supported by InfraRuby excludes metaprogramming and reflection.

Because 1. give away your work 2. ??? 3. profit! is not compelling :-p
