Whilst not something to be done if you value efficiency, you could use
Filter::Simple and PPI. I've been writing a module that needs to do more
than can be achieved with overloading and so have tried this out. Using
PPI, you can inspect the parse tree for interesting constructs, and then
rewrite them as function calls to carry out the new behaviour at
runtime (yes, I know this is a bit icky).
