Unfortunately, it's not always possible for the GUI to know that
the user clicked on a function name. The user actually clicked on
a line where a function happens to be defined.  With GNAT, some
information is available for the GUI to use once the program has
been compiled, but not all languages provide that type of info.
This is why your suggestion would be relatively difficult to
implement in a way that would be "intelligent".

Right now, if you take GPS (AdaCore's GUI) as an example, if you
want to break on a function (using its name), you have to use
the contextual menu after right-clicking on the function name.
If you want to click on a specific line, just click on it.
Breaking on a function by name is therefore a little more effort
than breaking on a given line, which explains why most users
just click on line numbers.
