re: operator precedence Io uses Operator Shuffling to move those operator method calls back into normal mathematical expectation (or to be exact... C precedence order) prior to building the AST. Ruby's parser must do (or does) something similar. From lmm answer it sounds like Scala does something similar to Ruby here. Smalltalk, Self & Rebol have no operator precedence and simply interpret the operators from left to right (using parenthesis to enforce higher precedence).
