Bug 17013 – JSC can't round trip certain for-loops

• Status: RESOLVED
• Resolution: FIXED
• Component: JavaScriptCore

[Oliver Hunt]

Given the code
function f(){
    for (var x;;)
        ;
}

f.toString() produces:
function f(){
    var x;
    for (var true;true;true)
        ;
}

in which "Var true" is invalid.

I wasgoing to suggest making additions to fast/js/function-toString-parentheses.js

But your choice seems much better
