243	Add warning for thread casts in constructors	Thierry Delisle		"When not using the thread keyword, thread casts are unsafe in constructors.

The following code for example:
{{{
struct SomeThread {
	$thread self;
	// ...
};
// ...
void ?{}( SomeThread & this, /*...*/ ) {
	((thread&)this){/*...*/};
}
}}}
leads to undefined behaviour because the constructor of 'self' will be called twice. 
We should add a warning or error for this. An easy fix would be to warn against thread casts in the constructor, but that could lead to many false positives. A better but harder approach would be to detect the case where this breaks, but that requires some amount of tracing through resolved code."	enhancement	new	minor	cfa-cc	1.0		thread cast
