The issue is these days everytime I hear optional I think of semicolons in JavaScript where they are optional except for one or two edge cases I can't remember off the top of my head. Optional is good as long as its a complete you can do it this way or that way like gradual typing in some languages.

Indeed. I meant really optional, not something like automatic semicolon insertion, where they are there, they are required by the grammar, but you are allowed to omit them in some cases.
