Even c and asm use existing libraries.
This is more inline with Samurai_crows project. Its not really much different than SDL, opengl, etc. (Only I suspect less of a fully fledged api).
Different kettle of fish to something like backbone.
As Mrs. Beanbag said, you still have to code it yourself.
As for blitz, well, fewer restrictions there as it let's a user use existing APIs.... Cgx, p96, ahi, SDL, opengl,.... whatever.
