Tryout Nim, it has powerful comptime/metaprogramming, statically typed, automatic memory management and is as easy to program as python or javascript while still allowing low level stuff.
For me it'd be hard to go back to languages that don't have all that. Only swift comes close.
D comes close ... it too has a full-language comptime interpreter and other metaprgramming features (though not as rich as Nim's), statically typed, optional garbage collection, and you can write
#!/usr/bin/env rdmd
[D code]
and run it as if it were an executable. (The compilation is cached so it runs just as fast on subsequent runs.)
