A bit off-topic, but hopefuly it'll help someone:

1. (In C,) one argument operators have binding tighter than two (or three) argument
    operators. (The only exception to this rule is the :: operator in C++ which has
    the tighest binding of all operators.)
2. The next rule, is that one argument postfix operators has tigter binding
    then prefix operators, thus *a++ is *(a++).

I find those two rules let me understand most operatrs use cases.  Hope this
helps. :)


Also, I haven't followed the patch from the beginnig (just stumbled accross
some mails), but anoter possible solution to the problem would be to change
the type of "value" to "bool".
