AnyEvent::Subprocess::Role::WithDelegates::Manager - manage delegate shortcuts
Creating an instance of a delegate to pass to
AnyEvent::Subprocess's constructor is tedious.
This module maps sugary names to builders of delegate objects,
so that the user can say
'Foo' instead of

None by default,
but you can request
$builder to build delegates named
$builder is a coderef that is eventually called with the key/value pairs supplied by the user.
(The docs say this has to be a hashref,
but it can actually be any scalar value.
Checking is up to you.) The builder must return an instance of a class that does AnyEvent::Subprocess::Delegate,
although this condition is not checked by this module.
(You will get a type error when you are building the class that uses the delegate.)
In the common case where the args should be passed directly to some class' constructor,
you can just supply the class name as the

or it can be a hashref or arrayref of name/args pair.
