I know somewhere is a collection of extensions to the enumerable module.

Is the rubygarden page

http://www.rubygarden.org/ruby?Stand...ons/Enumerable
the only one?

Anyway, I have just added FirstEachLast to that.

Use it like so...

require 'FirstEachLast'

def test_first_each_last(any_enumerable_object)

result = nil

count =

any_enumerable_object.first_each_last( proc {|first|

result = "First #{first}"

},

proc {|i|

result += " then #{i},"

},

proc {|last|

result += " and last of all #{last}"

},

proc {|| result = 'Empty!'}

puts count

puts result

end

test_first_each_last( [1,2,3,4])

test_first_each_last( [])

Will result in the following output...

4

First 1 then 2, then 3, and last of all 4

0

Empty!
