[Bug translator/3887] Need a syntax to specify probes alternatives

It is an interesting idea.
One thing to consider though is that the different probe points are unlikely
to be completely interchangeable.  Specifically $target variables available at
each variant may be quite different, requiring different handlers.

So how about associating the handlers with the alternatives?

probe kernel.mark("foo") { $arg1 ; $arg2 } ||
      kernel.function("bar") { $var1 ; $var2 }

or even with less punctuation:

probe kernel.mark(....) { }
else kernel.function(....) { }

Another issue to consider is what to do with aliases.
