"2 days" evaluates to a duration of 2 days but,

"2 day" evaluates to a duration of 1 day.

I've been thinking about it, and I think I can understand who this came about, but silently giving a user the wrong answer if they mistype "days" or write some code like "[ :n | n day ]" (I did this one) seems wrong. If "day" should only answer with the singular value, than perhaps it should throw an exception for any values other than -1 or 1. 

I'd actually prefer it just called days, and damn English grammar.

So what do you think, should I enter a defect or not?

(Also I'm new to the community, so I wasn't even sure where I should ask a question like this!)

Cheers,

Edouard.
