#["LÓGICA DE PROGRAMAÇÃO" É BOBAGEM, e explicarei porquê.]

Se preparem que o texto é longo.

Várias vezes chegam novatos aqui perguntando como começar, e a galera diz "estuda lógica primeiro, depois vai pra linguagem X". Vivo dizendo que é bobagem. Ontem, em particular, falei isso, e vieram várias pessoas por inbox me perguntar porquê (e uma pra me xingar, achando que falei por arrogância).

Pra facilitar, eu vou escrever uma boa explicação de porquê "lógica de programação" é furada, doa a quem doer, e postar na APDA e no fórum da EnergyLabs (para futuras referências, porque esse assunto vai voltar, ctz).

Rich Already Answered That!

A list of commonly asked questions, design decisions, reasons why Clojure is the way it is as they were answered directly by Rich (even when from many years ago, those answers are pretty much valid today!). Feel free to point friends and colleagues here next time they ask (again). Answers are pasted verbatim (I've made small adjustments for readibility, but never changed a sentence) from mailing lists, articles, chats.

How to use:

• The link in the table of content jumps at the copy of the answer on this page.
