thanks you both for explanations, it helps a lot :-)
two things should be corrected to converget o UNIX `cat':
* by default, stdin should be copied to stdout if there's no arguments;
that's easy with
(unless (argv)
(in @
(echo) ) )
* by default, many derivative cat use single, bare dash (`-') to stand for
/dev/stdin, but picolisp (the interpreter) seems to skip arguments after first
bare dash. is there any way around it?
cheers,
