You can do it at least three ways. Maybe more.
With invoke-expression:
$foo = "bar"
Invoke-Expression "`$$foo = 22"
with Set-Variable:
Set-Variable $foo -Value 22
Using New-Item is left as an exercise for the reader.
Of the choices, I would suggest that Set-Variable is easiest to read and
comprehend. :)

How does one leverage the evaluated output from some expression as the name of
a new variable?
For example (simplified):
$foo = "bar"
$bar = 22
Write-host $"$foo"
22
Thanks!
