Both Rebol and Red use that convention. It sounds weird at first look, but proved to be a relief in practice (no need to remember any specific precedence rule).

Both Rebol and Red use that convention. It sounds weird at first look, but proved to be a relief in practice (no need to remember any specific precedence rule). Though, we plan to provide a small math-oriented DSL for writing expressions using standard math conventions. It would look like this: >> print 1 + 2 * 3 == 9 >> print math [1 + 2 * 3] == 7
