It would be better objects were decorated in Scheme.

Here's the way it is:

§ "cat" cat

§ #\a 'a'

§ #t true

§ #(a b c) [a, b, c]

§ (vector "a" "b" "c") [a, b, c]

§ (make-vector 3) [#!undefined, #!undefined, #!undefined]

Here's how it would be if the input syntax matched the output syntax:

§ "cat" "cat"

§ #\a #\a

§ #t #t

§ #(a b c) #(a b c)

§ (vector "a" "b" "c") #("a" "b" "c")

§ (make-vector 3) #(0 0 0)

I'm actually okay with using true/false instead of #t/#f because that is also accepted as input.

Updated in r158

Strings, characters, true/false, lists, and vectors have been handled.
