Equivalent of the programming return; ?

Brand new to Twine, I'm starting to experiment a little bit with branching narration and the likes.
Being a programmer, I find the logic of Twine / Harlowe both very useful and very frustrating.

My issue is the following:
I have a bunch of (if:)/(else:), and I'm sure you all know these things can start to be a relative spaghetti-mess of code and lines if you need a numerous very specific cases in 1 single passage.
On top of that, I suddenly have a new condition, that if fullfilled, would simply skip over all the others.
The obvious way of doing that, which the little knowledge of Twine / Harlowe I have, would be to add that if/else encompassing all the others. That's okay, but what if I need to add encompass only a part of the others? What if my condition gets more complicated, and have to deal with some of the other if: before being processed (and then completely skip whatever is remaining to do).

As I said, I'm a programmer, so if I would have to do that while coding, I would usually put my new if at the very top (or at the relevant place), and then put a return; to end the function here and skip all the rest.

Is there an equivalent for that programming return; in Twine?
If not, why?
