Powershell is object oriented and, in my opinion at least, an absolute pig for doing quick one liners (overly verbose syntax, pipelines bork if types mismatch even when the data getting passed is still essentially just textual). I wanted something that was still in the same realm of typical UNIX shells (even with Bash comparability where sensible) but with an awareness of complex data formats.

However everyone has their own opinions and preferences. I wrote my shell to scratch my own personal itch and if others like / use it that is a bonus.
