I don't like to declare the same variable more than once.
Oops. It's so easy to slip... But on the other hand, you have to misspell the variable throughout all of &write_cache, which usually isn't too probable. But for short routines--like get/set routines--it's a not too far-fetched scenario.
For those times I prefer to use
The only reason I want more education is that I learned about lexical and package variables as totally separate!!! and now they ain't... Which is cool, but also pretty bizarre.
I agree, it does indeed look like globals has become... something else. But you can relax--they haven't. They're still totally separate. What our() does is to declare a lexical alias for the global variable.
