Re: [parenscript-devel] Bug: incorrect JS emitted for binary operators with more than 2 operands

I ran across this bug a long time ago. The equivalent of (> x y z) in JS would be (x > y) & (y > z). 'y' is evaluated multiple times, so you'd need to introduce a temporary variable for it. I wonder if there is any other approach (other than limiting the comparison operator to two arguments)?

PS generates code for expressions like (> x y z) as if the operators worked the same way in JS and Lisp, but they don't. For example,

(ps (> 3 2 1))  => "3 > 2 > 1;"

... is an expression that is true in Lisp but false in JS.
