Yes, you can make some guesses about the names of passed values
provided you're ok with extending the code in Devel::Caller's method
for asking whether your code was called as a method or a function. In
general, this code is too ugly to live. You're adviced not to solve
this problem in Perl 5. The general solution will eat your brain and
only a handful of people on the planet will be able to maintain it.
code crashes. They're hard to debug. And I don't know how to do
