You could notice that syntaxes 2,4,6 are "=>{" which means that 
what follows next is return value, not body of function, i.e they 
don't do what is expected but return delegates which do what is 
expected. You need to wrap them into ()() to make them work.

By the way, strictly speaking they are template lambdas.
