We haven't talked about bash features like

!:1 !:$ yet

!:1 means first argument of last commands, !:$ means last argument of
last command

Some kind of completion could also be achieved by using this
completion:: IO (a) -- a in this case Filename

liftM cat completion

where is a function (or another program) with it's own interface...
beeing executated after pressing enter..

A haskell shell would be nice because you could also do something like
this (in the manner of formIntegral) :

dvd <- (fromVideo viedo.mov))::MyDVD
butn dvd  >> mkiso dvd
;) Wow!!!
You would be able to assemble common task in a new, type-safe fashion.

fromVideo of cause would itself call something like mplayer or
