Then [ shadows the sh executable aliased from ‘test’ so that you can no longer do [ some conditional ] && ... But have to write test some conditional &&

  That's true. In shells, "test" and "[" are often used after "if", as for example if test -f "some_file" do_something fi if [ "$FOO" != "" ] do_something_else fi Schemesh does not have a shell builtin "if", you switch to Scheme for that: (if (file-regular? "some_file') (sh-run {do_something})) Thus the need for "test" and its alias "[" is reduced. Also, "test" implements a mini-language full of one-letter operators: `-f FILE` `COND1 -a COND2` `COND1 -o COND2` etc. I really don't miss it, as I find the equivalent in Scheme to be more readable - and of course more general (file-regular? "FILE") (and COND1 COND2) (or COND1 COND2) etc.
