It looks like the generator is suboptimal, but still really cool. (![]+[])[+!+[]] evaluates to "a" as well. It looks like it turns it into an array twice. It goes +!+[] === 1 then [+!+[]] === [1] then +[[+!+[]]] === 1 then [+[[+!+[]]]] === [1]

Ah! You're right. Confusing. Also confusing that "false"[[1]] works.

Maybe one could run the output through Closure Compiler to get a bit better code ;-) (Ok, tried it, it evaluates plenty of numbers on its own already which increases the character set. Not nice).
