When programming with callbacks in perl, you create anonymous functions with
|
|
sub { ... }. These functions are especially useful because when they are called
|
|
they 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.
