Lucid

Mais uma ótima dica do amigo Orsoni: Lucid. 

" If you have a chance, try googling “esoteric programming languages”, “befunge”, “brainf**k”, “unlambda”, or “thue". 

Lucid proposes a completely different model. You look at the flow of data, not the flow of control. It can be considered a "dataflow" language.
