Function parent scope

If a module function creates a variable in the parent scope then the variable is created in the module scope, not necessarily the calling scope.

• Module1.psm1 exports the function New-Variable1 which creates a variable in the parent scope.
• Test-Module1.ps1 calls New-Variable1 and fails to get the variable Variable1 in the current scope.

If a script function creates a variable in the parent scope then the variable is created in the calling scope.

• Script1.ps1 defines the same function New-Variable1, as Module1.psm1 does.
• Test-Script1.ps1 calls New-Variable1 and gets the variable Variable1 in the current scope.
