1. Yes, but there are little reasons to use brainfuck in production code, and there are reasons to use POSIX shell: 1. It is available on practically all UNIX-like systems from NetBSD to Ubuntu in their default installation (no additional dependencies) 2. For small scripts it can run faster than Python/Ruby/Perl thanks to small startup time. 3. It is a handy tool when all you need a small script which mostly runs other commands/CLI tools (but you still have to spend at least little time to learn it first). May be availability of the shell is an unfortunate historical artifact, yet it still the reason why one may want to use it. 2. Idea to impose elegance upon users is attractive, but even if we ignore that it makes system/language design harder, different people can have different option on what is elegant and what is not. Having said that I like Go (which tries to enforce what can be enforced) because options of its author are not too far from mine. But not everybody is happy with Go and it is not hard to find its criticism.
