What if there was a less cryptic way to have mandatory arguments, something harder to get wrong, like

  param(
    [parameter(mandatory)] $name
  )

  "Hello, $name!"

And then:

  $ ./script.ps1 Dave
  Hello, Dave!

  $ ./script.ps1 -name Dave
  Hello, Dave!

  $ ./script.ps1
  cmdlet script.ps1 at command pipeline position 1
  Supply values for the following parameters:
  name: <cursor here>

Or non interactively:

  $ pwsh -nonint ./script.ps1
  script.ps1: Cannot process command because of one or more missing mandatory parameters: name.
