Borges is totally recommended, of course, but after reading him in the original language I think his English translations lack the poetry and music of his writings. For once I am happy Spanish is my first language.
With AI tools, though, I can "read" Borges in his native language: with my phone + OCR + translate I have an English language companion. Or, using the voice interface I can try narrating the Spanish text and ask clarifying questions whenever I'm confused.
An author like Borges makes it well worth the extra effort. And, his puzzles often involve language, so the extra layer of mental translation can mirror the work itself, e.g. in his poem La luna [1]. (though, I envy your native Spanish)
On these conjugations, compound verbs are not hard at all.
(I agree!)
