##
  # A FileList is essentially an array with a few helper methods defined to
  # make file manipulation a bit easier.
  #
  # FileLists are lazy.  When given a list of glob patterns for possible files
  # to be included in the file list, instead of searching the file structures
  # to find the files, a FileList holds the pattern for latter use.
  #
  # This allows us to define a number of FileList to match any number of
  # files, but only search out the actual files when then FileList itself is
  # actually used.  The key is that the first time an element of the
  # FileList/Array is requested, the pending patterns are resolved into a real
  # list of file names.
  #

# == Method Delegation
    #
    # The lazy evaluation magic of FileLists happens by implementing all the
    # array specific methods to call +resolve+ before delegating the heavy
    # lifting to an embedded array object (@items).
    #
    # In addition, there are two kinds of delegation calls.  The regular kind
    # delegates to the @items array and returns the result directly.  Well,
    # almost directly.  It checks if the returned value is the @items object
    # itself, and if so will return the FileList object instead.
    #
    # The second kind of delegation call is used in methods that normally
    # return a new Array object.  We want to capture the return value of these
    # methods and wrap them in a new FileList object.  We enumerate these
    # methods in the +SPECIAL_RETURN+ list below.

# List of array methods (that are not in +Object+) that need to be
    # delegated.
    ARRAY_METHODS = (Array.instance_methods - Object.instance_methods).
      map { |n| n.to_s }

# List of additional methods that must be delegated.
    MUST_DEFINE = %w[inspect <=>]

# List of methods that should not be delegated here (we define special
    # versions of them explicitly below).
    MUST_NOT_DEFINE = %w[to_a to_ary partition * <<]

# List of delegated methods that return new array values which need
    # wrapping.
    SPECIAL_RETURN = %w[
      map collect sort sort_by select find_all reject grep
      compact flatten uniq values_at
      + - & |
    ]

DELEGATING_METHODS = (ARRAY_METHODS + MUST_DEFINE - MUST_NOT_DEFINE).
      map { |s| s.to_s }.sort.uniq

# Now do the delegation.
    DELEGATING_METHODS.each do |sym|
