I've been on holiday since I left my last reply so also getting back late on this :) Everything in Rebol is just blocks of words, where (in general) expressions are evaluated from left to right; however, within each expression evaluation occurs from right to left [1]. So (infix) operators are also just words and have no precedence order so they just evaluate left to right (like Smalltalk) when parsed [2]... >> 1 + 2 * 3 == 9 To enforce any precedence you use paren! blocks [3], which are blocks that get evaluated immediately. >> 1 + (2 * 3) == 7 refs: [1] http://www.rebol.com/r3/docs/guide/code-eval.html http://www.rebol.com/r3/docs/guide/code-eval.html [2] http://www.rebol.com/r3/docs/concepts/math-precedence.html http://www.rebol.com/r3/docs/concepts/math-precedence.html [3] http://www.rebol.com/r3/docs/datatypes/paren.html http://www.rebol.com/r3/docs/datatypes/paren.html
