Well, I just checked, and with "out" and "var" for a getter with an array
property it actually doesn't compile if you pass a literal. Which is good
as at least it behaves logically.

That said, I'm unsure why setters need a directive, but getters do not.
(Even constref works fine, with no directives, currently, for getters.)

If anything, what would make the most sense is to just have a {$VARPROP}
directive that enabled all of the "by reference" stuff for both getters
*and* setters, while otherwise restricting them both to only "const",
"constref", or "unprefixed" parameters.

{$VARPROPSETTER} presumably needs to also be left as-is for Delphi
compatibility, but that's not really a big deal either way.
