Great library, very useful stuff and absolutely love the size. :) I've only recently started learning about and took a look at the source code. So apologies in advance if I am wrong ;). 2 things caught my eyes: So if we do something like the following snippet (taken from the README), it seems that each new function instantiated via will reserve a new thread and a new URL reference. So, if there is a case wherein I don't need to use after a certain point in my code, those resources are still trapped. They may be very less in size to be of a practical concern, but I am not sure about it and would love if anyone can comment on that. However, if the output function comes with a method which releases those references, it could be useful. WDYT? Something like: Internally, it could call: Post , can itself become so it's not callable. Or can a more informative error: . Is there a downside to this approach if the contributors already considered any similar approach?
