When programming with callbacks in perl, you create anonymous
functions with sub { ... }. These functions will preserve their
surrounding lexical environment. Sometimes people call these
anonymous functions that reference variables in their surrounding
lexical scope "closures". Whatever you call them, they are essential
for convenient and efficient asynchronous programming.
For many applications we really like straightforward callback style.
The goal of Callback::Frame is to simplify the management of dynamic
environments while leaving callback style alone.
