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

[shmem]: some experience with vim?
[Lady_Aleena]: None
[shmem]: I don't know geany, and don't know whether it has support for ctags.
[Lady_Aleena]: ctags?
[shmem]: ctags is a program which (recursively) extracts the symbols from source and stores them in a one-file database. This allows you to query the locations where these symbols (e.g. a subroutine name) are used anywhere in the source code tree...
[shmem]: ...from inside the editor.
[shmem]: apt-get install exuberant-ctags
[Lady_Aleena]: I think I heard vim has a big learning curve.
[shmem]: then in the root of your source tree run: ctags -R
[shmem]: you get a file named tags where all symbols and the places where they are used are listed
