True, but if double = 3 (in which case the keyword is also considered "set") the type
would be wrong (a string array!).

I don't know why users would do double = 3 in the call, but, in my experience at least,
I've seen 'em do stranger things..... (me included of course - probably the worst offender
actually :o).

Works on my linux box too. I just want the behaviour blessed via some RSI documentation.
Without that, I'm assuming it's pure luck.
