Right, I forgot about the return; so I've striked off my question about no_implicit_return.

As for implicit_return, I guess I got confused as to the purpose of the if statement. Both the true and false code paths lead to an implicit return of the call to tst_context. Me thinks why bother having the if at all? :-)

    The if shows that multiple statements can be returned implicitly and it's not necessarily the undermost statement.

    If you know of a better example illustrating this - at the same time non-trivial and not complex - I'm open for suggestions. :)

    There is a whole bunch of "Flow-Control-Statements" which could play a role here.

    Cheers Rolf
