| Subject: | A wishlist of some API changes in Async::Defer |
Here is my wishlist of API changes that may improve the usability of
this module.
1. I wish do() method accepted multiple tasks as a list parameter,
like $d->do(@tasks); which is just a short-hand of calling do()
multiple times.
2. I wish run(), do(), if() and other statement methods returned the
Async::Defer object. That way, we can use method chaining to
describe an async program like::
my $d = Async::Defer->new()->do(sub {
...
})->if(sub { ... })->do(sub {
...
})->else()->do(sub {
...
})->end_if()->do(sub {
})->run();
3. I wish run() method accepted a coderef as well as a parent defer,
because I want to treat $d->run() as just another async function
that calls the user-given callback when it's done.
I think $d->run($coderef) might as well be equivalent to::
my $callback_defer = Async::Defer->new();
$callback_defer->do(sub { my $this = shift; $coderef->(@_);
$this->done });
$d->run($callback_defer);
The above wishlist is just small changes in API spec, but I believe it
significantly helps reduce redundant codes such as multiple occurrence
of $d->... and ephemeral named variables like "my $callback_defer".
