Idiom # 100: Sort by a comparator

See programming-idioms.org:

Code

items.sort c

What are effects?

Running Example

ex100 is

  items := [ "siebenundvierzig";
             "elf";
             "null";
             "acht";
             "fünfzehn" ]

  c (String, String) -> bool := a,b -> a.byte_length <= b.byte_length
  say (items.sort c)

  # passing the lambda directly to sort avoids
  # specifying its type:
  #
  say (items.sort (a,b -> a.byte_length <= b.byte_length))

What are effects?
