I Spy Integer#times_collect

The method #collect, or its alias #map if your prefer, is one of the most useful methods in Rubyland. You see it all the time. Unfortunately it isn't applicable to a number of common variants of iteration. One of these is Integer#times. So Facets provided just such a method.

  require 'facets/integer/times_collect'

  bottles = 99.times_collect { |i|
    "Bottle of Beer No. #{i}"
  }

This is also aliased as times_map. But if either of these method names strikes you as too long then you might find this alternate (required separately) more convenient:

  require 'facets/integer/of'

  bottles = 99.of { |i|
    "Bottle of Beer No. #{i}"
  }

Take one down, pass it around!
