foo >>= bar executes the action "foo" and passes its result to the function "bar" (which must then return another action, which is executed). foo >> bar executes the action "too", and then executes the action "bar". Any result generated by "foo" is discarded, and "bar" must be an action rather than a 1-argument function that *returns* an action. Make any sense?
