Two options for script-per-function module design

dotSourcing.ps1

# Works fine in "normal" environment, can become slow when network is more complex...:
foreach ($file in Get-ChildItem $PSScriptRoot\*.ps1) {
    . $file.FullName
}

# Should be fast everywhere, but it's bit more complex...
foreach ($file in Get-ChildItem $PSScriptRoot\*.ps1) {
    . (
        [scriptblock]::Create(
            [io.file]::ReadAllText($file)
        )
    )
}
