Wishlish: GCC option for explicit booleans

[pl@nch.com.au]

C++ would be a better language if the boolean type did not implicitly
convert from int. For example, many novice programmers make the
mistake.

   if (i = j) dosomething(); // Should be i == j

If conversion to boolean required explicit this would all be solved. It
would mean all the old code with expressions like "while (p) ... "
would need to be changed to "while (p != NULL) ...". But I think the
change would be well justified.

What about a GCC option to turn off implicit conversion to boolean?

I for one will require all code written in this company to use the option.
It would save many bugs.

Note: C# does this. While I don't like C# - it is one good feature.
