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

[Vladimir Sedach]

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)?
