int and logical &&

No, Monkey C implements "&&" and "||" differently for numbers, last time I checked. See the link below:

TL;DR:

A && B => A & B

A || B => A ? A : B

        var x = 129, y= 2;
        if(x)         {LOG.println(true);} else {LOG.println(false);}
        if(y)         {LOG.println(true);} else {LOG.println(false);}
        if(x && y)    {LOG.println(true);} else {LOG.println(false);}
        LOG.println( (x && y) + " " + (y && x) + " " + (x & y));

true
true
false
0 0 0

I've just tested it, javascript returns the last operand and monkey c result of | operation

so for (2 || 129) js returns 129, for  (129 || 2)  returns 2  but always not 0 like monkey c

Of course the problem is that unless you're using Monkey types, you can't check the type at compile-time...

Well, IMO it should be a compile-time error (when using && or || on numbers), which avoids any issues with existing code breaking at run-time.

The worst part is that && of two numbers is logical AND but || is not (it works like javascript and returns the first operand which is not falsey).
