is it possible to expand via squared-bracket.

i.e... [1 2 3] => (list 1 2 3)     [(+ 1 2) 3]  => (list (+ 1 2) 3)


I know (read-enable 'square-brackets) ...but It just same paren.

[1 2 3] => (1 2 3)

is it possible?

The closest thing is read-hash-extend:

You can have a look in here to see a more sophisticated example:

(however, I do not recommend to use such extensions)
