Unfortunately, we can't ever change that one, or the whole world of existing stuff will break.

It's intended as a shell semantic where anything bare on the command line just gets run, no matter your scope.

However when we introduced classes, we thought it was a more "dev-oriented" semantic, so we changed return there.

This will only return 'this will return':

  class foo {
    [string] ReturnTest() {
      'this will not return'
      return 'this will return'
    }
  }
  
  ([foo]::new()).ReturnTest()
