blocks

Ruby has blocks, flor is closer to Javascript, it needs functions.

Blocks are nicer, especially for non-programmers. Non-programmers will probably have a look at the flows. Blocks might help.

schedule and its macros

schedule  #### needs function

  cron      #
  every     #
  at        #
  in        ## accepts blocks, transforms into "schedule"

cron '0 0 1 jan *'
  task albert 'take out garbage'

is turned into:

schedule cron: '0 0 1 jan *'
  def msg
    task albert 'take out garbage'

trap and on

on 'approve'
  task 'bob' mission: 'gather signatures'

is turned into:

trap point: 'signal', name: 'approve'
  set sig 'signal'
  def msg
    task 'bob' mission: 'gather signatures'

"on" traps signal.

map and co

Use the ect procedure for the "block" versions. Use the FP "classical" name for the "func" versions.
