## TRY: Pipelining | |
$characters | foreach { $_ } | |
$characters | foreach { $_ } | select -f 3 | |
## CRY: Looping | |
foreach ($_ in $characters) { $_ } | |
foreach ($_ in $characters) { $_ } | select -f 3 | |
## FINALLY: in terms of readability and clarity, you should always do it like this: | |
$characters | ForEach-Object -Process { $_ } | |
foreach ($character in $characters) { $character } |
