ACK.  That is what I thought of Scott's argument, along the lines of “red 
herring” or even “strawman argument”.

Yes, I think we have already agreed on that.

I do not follow.  If the code is almost never executed, and it covers an 
unusual edge case, then there would be few occurrences of it and the amount 
of space saved to replace few “true” with “!0” would be negligibly small.  
Also, I am puzzled by your reference to unnecessary “client-side 
debugging” – where else would you debug code that runs in a browser?  Are 
you just joking after all?
