I have a different vision for future shells: https://github.com/ilyash/ngs/ . Using one of the existing languages has obvious advantages but it's not a domain-specific language for system tasks so it will never be optimal for that. Making DSL on top of an existing language also does not sound like an optimal solution. My approach is a domain specific language which specializes on system tasks and has small simple bash-like syntax mode and "normal" programming language syntax mode. The two modes are easily mixed.
