Using the array operator to break up lines

The array operator, @(), can break up arrays that are used as arguments into operators, or values for parameters.

For example, the format operator, -f, may be used in place of sub-expressions or variable interpolation. @() may be used to define an array to hold the arguments for the operator. The following example shows two different ways of creating the same string:

$item = Get-Item C:\Windows\explorer.exe# Sub-expressions and variable interpolation"The file, $($item.Name), with path $item was last written on $($item.LastWriteTime)"# The format operator'The file, {0}, with path {1} was last written on {2}' -f @(    $item.Name    $item    $item.LastWriteTime)

The same approach may be used for replace operations ...
