if (bool) // checks for bool=true

why

if (notvaluetype) // can't check for null, instead complains not being bool ? i find this very annoying

It's *great* not to allow "if" to work on anything other than bool, in my view. It means there's no point in writing comparisons the "wrong" way round as you sometimes see in C/C++:

if (5==x)

The above is to avoid the typo of:

if (x=5)

- but in C# the latter doesn't compile anyway.
