OK, why are we making a fundamental distinction between scalar and list variables via the sigil, when they seem to behave identically? A scalar can hold a list, and the explicit "reference" concept is no longer used, and the only difference is that you can leave off the parens when assigning a literal to the list variable.

Given that scalers can hold arrays, why bother with making @variables different, or using them in code?
