I’m trying to use the dry-system auto-registration to create some objects that “should” be singletons, though I don’t want to force them to be at a code level. For example I might have some sort of domain-aware cache that I want to have injected, and every time it gets injected it should have the same underlying object.
If I have a trivial object that exposes
#h as a Hash and make that auto-registered, I can readily see that the data isn’t getting shared, like
Application[:component].h[:k] = :v v = Application[:component].h[:k] print v ? v : "[nil]"
(Complete example at https://gist.github.com/dmaze/1cb828a47045b2214a1491fc34cb6144)
Is there a convenient way to make the auto-registrar provide a single instance of the object to all consumers, instead of having it get recreated on every call?
