Igor,
What would you expect from the following: #(1)? Should it be (Array
with: 1) or (Array with: #'1')?
I think that the assumption is that you should be able to include any
literal constant (including SmallIntegers) in a literal constant
array. I think of #(foo) as a shortcut for #(#'foo'), where the second
form is more explicit. If you want to avoid the ambiguity, then always
be explicit when you want a symbol.
