This is actually a great point.

Totally. IMO it's equivalent to deciding whether to write a book in your native language or in another language you don't speak because they have more words in the domain of the book's topic.

You wrote this in English? What kind of comment-writer are you? English has so many spelling inconsistencies and homonyms it's a wonder that anyone can understand anyone else. Everyone knows that real authors write in Spanish. Neruda, Borges, Márquez. Spanish's clear pronunciation rules, elegant conjugations, and separation of mutable state (`estar`) from immutable state (`ser`) ensure you'll never run into any dangerous misunderstandings. Consider this sentence:

    "¡Hola, mundo!"

Note that the sentence is one character shorter than the corresponding phrase in english (`"Hello, world!"`) - this kind of efficiency is quite common when you write in Spanish. Also note that the extra space won by removing a character was then used to add a pre-exclamation flag (`¡`). This flag is a neat optimization to ensure that the interpreter knows to prepare for an exclamation ahead of time.

Better interpretation, pronunciation, efficiency. Why are you not writing Spanish today?
