+, - and such

[Jonathan Hseu <vomjom@xxxxxxxxxx>]

Is there a reason why + and - currently take only two arguments?
According to the manual, the definition for them is:
(x|<num> y|<num> => <num>) 

Would I have to do awkward stuff like:
(- 0 x) to negate x?

Or nest additions to add multiple times?

Or is it a temporary thing?

Potentially stupid question :)
