After puzzling over your intro briefly, it appears to me that you see
the additional space as being significant in distinguishing between your
two examples:
(1) With space
>>X: ["a" "b" "c"]
>>
>>
== ["a" "b" "c"]
and (2) without space
>>X[2]
>>
>>
== "b"
Notice, however, that the colon is also missing in example 2. I.e., even
if you were not to supply the extra space in example 1, i.e.
>> X:["a" "b" "c"] ;- example 3
you would still have the significant distinction to example 2 in that
in example 3 you again have the colon separating the X from the block ,
whereas in example (i.e. X[2]) there is no such colon.
