me. I notice, however, that Marko Mikulicic has a posting on the topic here: <http://groups.yahoo.com/group/iolanguage/message/7141> A short description of the problem is this: Io to some degree allows us to write arithmetic expressions with operator precedence as in C or FORTRAN, but when an operator is followed by a parenthesis, the operator "forgets about"; precedence rules and acts as a normal Io method. This can of course be confusing for a newbie, and as far as I know there isn't much to be found on this behavior in the Io docs. My example is this: 1 + 5 * 4 ==> 21            // expected 1 + (2 + 3) * 4 ==> 24            // you see? Some of you may say it's the way Io should be (and forget about FORTRAN), others may say it's a bug that should be fixed. My main concern is that the "Io authorities" should make a decision here, and put it in the docs. There are persons working on Io parser improvements right now, and you can't write a good parser if the specs are unclear! /Jon
