Error with the Lucky implementation

[wout]

When I include raven, my Lucky app fails to compile with the following error:

Module validation failed: Function return type does not match operand type of return inst!

Error: you've found a bug in the Crystal compiler. Please open an issue, including source code that will allow us to reproduce the bug: https://github.com/crystal-lang/crystal/issues

I already reported this at the Crystal repo, but do you have an idea how to work around this? I believe it has something to do with AnyHash. You probably know better where to look.
