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.
