I get an error here; x has no value. Did you mean to use 'block in that
expression and below, whereever 'x appears?
>> do block/1 returns 1, do block/2 returns 4. Thus it appears that even
though x has no value globally,
it can be "done", ie, evaluated.
Interestingly, if you precede your "code" with x: 25, it retains that value
after executing your first code line.
So the x's that appear in
>> block
[x x x x]
differ from the global x with value 25.
