Partial application is a common concept in functional/applicative
programming languages, which facilitates to get a closure over another
function where some of the parameters are already applied, e.g.
something like (pseudocode):

  incr = partial(plus, 1);
  print incr(2); // 3
  print incr(100); // 101
