BTW I have an idea - for gamedev could be beneficial to make some VM engine (multiplatform), for example like BEAM, why not, but probably something much faster (like LLVM), but including rich library of structures and algorithms for structured data and optimized for GD, and with good debugging tools for high level structures.

This may become gamechanger, as it could be very fast, but high level abstraction, so people don't need to dive into machine level, and could work on high level.
