C++ Habits

I came to the conclusion this week that I have at least one C++ habit I can’t kick. When I want to check an object reference for null, my fingers automatically type:

Widget woo = GetWidgetFromSomewhere();
if(woo)
{
    // …
}

Error: Cannot implicitly convert Widget to bool.

After five years of working together, the compiler still doesn’t understand me.

When looking at others' code if I see comparing to 0 on the left, that's a sign (to me) that they did C/C++ work at one time. I.e.,
 
 if (0 == x) { ... }
 
 as opposed to:
 
 if (x == 0) { ... }

I for one would LOVE for the C# compiler to support this syntax. I'm with you brother.
