My initial thought after seeing this is Windows support is interesting, but the real value is in making bash friendlier. Something that brings syntactic sugar to bash is welcome in my mind, as I always find myself putzing with Google to find solutions to even slightly non-trivial scripts.

Perhaps I should just master bash scripting once and for all (I know it's not that complex), but I generally find it unpleasant to do anything that requires control flow or traditional "programming language logic" in bash.

A simple way to bootstrap the compiler with the script itself would be especially nice. Basically, an embedded batsh compiler. Might be an interesting avenue for an enterprising person to look into.
