Hello, I'm using Harlowe in Twine 2.2.1 on a mac. When I attempt to use the (lowercase:) macro, it turns bright orange in the editor. When I run the game it gives me an error that reads: "I can't run the macro 'lowercase' because it doesn't exist."
This, for example, gives me the error message and prints $apple as "0":
(set: $apple to (lowercase: "APPLE"))
I've checked my spelling and even cut and pasted the example from the Twine wiki.
Is that macro not supported? Will it be soon?
Is there an alternate way to lowercase every letter in a string?
