(Instead of 3 it returns an op! value.) Anton.

Hi Anton, A> The above may be another aspect of a bug I A> have already reported: A> >> (+ 1 2) A> >> A> (Instead of 3 it returns an op! value.) Is + documented as allowing that notation? I thought it was strictly an infix operator, in which case it should flag an error about missing an operand, correct? -- Gregg

Yes, the math operators are special in that they *also* allow you to write them as infix operators. I think back in the mists of time they started out equal to all other rebol functions, only accepting the two arguments to the right. Then, due to popular demand they added the infix notation to them. Just try it, in any rebol except the latest view beta 1.2.8
