One of the reasons for using dash is speed. It's so fast, it allows people to write programs that were not viable before. The pure shell C compiler is an example of that: https://gist.github.com/alganet/2b89c4368f8d23d033961d8a3deb5c19 https://gist.github.com/alganet/2b89c4368f8d23d033961d8a3deb... It's portable among the most popular shells, but much faster on dash. It's obviously a gimmick, but also a way to stress the interpreters past their usual breaking points. osh fails at it because of multi-command/block-level alias (I opened an issue with a simplified reproduction). --- Options are good. Shell is amazing at that, lots of interpreters to serve all kinds of users and use cases.
