I'm generally supportive of the effort to replace the archaic shells that dominate the unix landscape, but unfortunately none have yet met my personal desires.

I'm generally supportive of the effort to replace the archaic shells that dominate the unix landscape, but unfortunately none have yet met my personal desires. It seems like a lot of the developers of these shells create them to supplement the common unix toolset, but I really want a complete replacement. Ideally, the shell itself would be a completely dependency-free static executable, with a built-in command set that includes functions to interface with all the kernel's user space accessible features, acts as a repl, with sensibly named commands, and a simple method for interfacing to and from any other program. In short, I guess I'm looking for something to act as the basis of a completely new environment on top of Linux. As it is, most of these do not even meet the first of the criteria.
