(move: $x's 1st into $y) doesn't work?
Hello!
Learning Harlowe Twine 2 from http://twine2.neocities.org/, and there is instruction about (move:) macro, which could be very useful for me.
"(move:): This macro behaves like (put:), but it requires both sides of the into expression to be variables, and deletes the left side after copying its value to the right side. In other words, running (move: $x into $y) will change $y to $x's value and delete $x. Its main intended use is with arrays: (move: $x's 1st into $y) will remove the item at index 0 from the array and set $y to it"
But! It doesn't work. Here is my script:
(set: $ar to (a: 1,4,5))
(move: $ar's 1st into $trash)
$ar
and here is an error: http://prntscr.com/7saht2
("You can only use positions ('4th', 'last', '2nd-last', etc.) and 'length' with a an array.")
What am I doing wrong?
P.S. Sorry for my english

If I add you example into a new story using Twine 2.0.8 and Harlowe 1.1.1 ... it outputs the following in Test/Play/Publish I suggest updating to latest version of Twine 2 and Harlowe.
