Okay that is easily rectified, we simply allow inheriting from the 
function body, not just called functions ;)

The reason it must support be declared in some form (which is how it is 
also represented in the AST) is due to it being value type. Its like as 
if you put a algebraic type for the return value with your declared 
return value + what can be thrown from it.
