Playing around with combining ":" and "."....

  arc> (= x [+ 10 _])
  #<procedure: x>
  arc> (prn:prn.x 5)
  #<procedure: x>
  15
  15
  arc> (prn:prn.x 5)
  #<procedure: x>
  15
  15
  arc> (prn (prn.x 5))
  #<procedure: x>
  15
  15
  arc> (prn ((prn x) 5))
  #<procedure: x>
  15
  15
Is this actually the way the first expression is being expanded? I can think of situations where I would want (foo:bar.arg) to be expanded to (foo (bar arg)) not (foo ((bar arg))). Just a thought.

I think it makes sense.

  arc> (def add (x) [+ x _])
  #<procedure: add>
  arc> (map [prn:add.40:idfn _] (range 1 5))
  41
  42
  43
  44
  45
  (41 42 43 44 45)
