So far as I'm understanding this thread, Steve Teale is asking
for a way to inject code before and after a call to a function
from other places in the program. E.g. Write some function
foo, write some function bar, and specify that any time foo is
called, bar should be called immediately after *automagically*.
The reason this hasn't been done in any language I'm aware of
is because you can solve the same problem using existing
polymorphism, and it's a horribly awful design practice to have
hidden code like that.
It's a bit more specific than 'from other places in the program',
and anyway, once you've accepted virtual functions, you've
accepted 'automagic' ;=)
I'm writing a little example program that illustrates what I'm
getting at, and I'll post it somewhere when I'm through.
