Interesting. [d==1] has a Cody size one greater than (d==1). Any thoughts as to why?

J.R.! Menzinger on 7 Nov 2014

The brackets are the operation "conatenate elements" so it is interpreted as an extra operation. The expression [1:10] has the same meaning (result) as (1:10) but in the first case you have done an extra operation (not necessary in this case). On the same way you can use [1 5] but if you use (1 5) you become an error because there is no concatenation with simple parenthesis.

Nice. Thanks for the explanation, J.R.
