alas, my imagination is lacking:

    system "bash -c ./s"

my point is that </> is a path constructor - it should isolate me from
/vs\, but nothing else; actually, since i often work in mixed systems, </>
should not even try to guess the direction of slashes for me, it should 
just allow me to abstract over that decision, so that i can make it in
a single place, consistently for all my paths (and if the next run or another
part of the same program wants the slashes the other way round, that 
should also be possible. if i want anything more intelligent, i can use 
normalizeXXX, where XXX specifies the norm of the day.
