Vista - The easiest way to create an empty data structure

I have discovered how to create an empty data structure very easily and yet
effectively.

----- 8< -----

# I guess this way is standard and verbose
function MyObject1
{
$e = New-Object PSObject
$e | Add-Member NoteProperty p1 $null
$e | Add-Member NoteProperty p2 $null
$e | Add-Member NoteProperty p3 $null
$e
}

# I guess this way is not standard and brief
function MyObject2
{
1 | Select-Object p1, p2, p3
}

# The results are the same
MyObject1 | gm
MyObject2 | gm

# The brief not standard way looks even more effective
Measure-Command {1..111 | % {MyObject1}}
Measure-Command {1..111 | % {MyObject2}}

Terminology:

I think “a custom object with null properties� is more correct than “an
empty data structure�.
