that is just evil code

if you got something todo before or on the first item of the list do it 
before the loop - and for the last behind the for loop

if we talk about code-duplication then - use an inner function

this type of sub-branching "de-looping" is slow (if performance is 
relevant) and just not foreach-able, and so not functional-style 
programming - its called "for loop index micro management for unknown 
reasons" - but many programmers prefer it very much :)
