# Deletes elements from self for which the block evaluates to +true+. A new
# array is returned with those values the block returned. So basically, a
# combination of reject! and map.
#
# a = [1,2,3]
# b = a.take_and_map { |x| x * 2 if x == 2 }
# b # => [4]
# a # => [1, 3]
#
# If +pattern+ is specified then files matching the pattern will be taken.
#
# a = [ 'bar', 'foo/bar' ]
# b = a.take_and_map('*/bar') { |x| x }
# b # => ['foo/bar']
# a # => ['bar']
#
# If +flatten_and_compact+ is +true+, the result array will be flattened
# and compacted. The default is +true+.
