Wrong character in wildcard pool throws confusing parsing error

BP(\x).free;
PR(\abstractLiveCode).chuck(BP(\x), nil, (
	defaultParm: \degree,

/x = "\ins("", ".", 16, 0.25)";

ERROR: Message 'item' not understood.
RECEIVER:
   Character 46 '.'

".", for a pitched parameter, is read as an articulation pool string, not an item string -- which is incompatible with item strings.

The fix, I think, will be for generators to publish expectations about inputs. Bigger fix than I can do right now.
