Bracket lists shouldn't be == to parenthesized lists

Currently bracketed lists in 3.5 are ==-equivalent to parenthesized lists with the same contents. This doesn’t match the behavior of lists with different separators, or the general principle that ==-equivalence should roughly track CSS equivalence.

To add some more detail: in Sass’s internals, lists never have parentheses. When you write (1 2 3), the parentheses mean the same thing that they do in (1 + 1)—they just group the expression. So the only question is whether a list has brackets or has no brackets, which is answered by is-bracketed().

Sorry for the short reply I’m on my phone. I think you’ll find most of the answers in sass-graph

@nex3 https://github.com/nex3 is there a list-separator() equivalent for checking if a list uses brackets vs parenthesis? Also, is an un-specified list like one two three forced into one of the two categories by default?

In True test output, we have to help users understand that lists can output the same inspect value, and still be unequal.
