implicit return does not commute

def func() { "hello" }

is not equivalent to

def func() { block: { "hello" } )

the former returns "hello", the latter "null".

The two are logically equivalent in every other respect, and probably should be equivalent in this respect, too.

It would also be nice if this worked as expected:

def func( test )
{
if( test )

else

}

Being a ruby-ite, I expect this to return "hello" or "goodbye", not null.
