If the long build time for static typing programming language is the concerns perhaps you can try have look at D programming language since it is optimized for fast compilation [1].
Around last year someone even managed to speed up its compilation time even further and it is also featured in Hacker News but cannot find the link now.
I think in the future most of the static typing programming languages will be mainly based on Single Static Assignment (SSA) technique then the compilation could really fly.
