Enum ForHead 

pub enum ForHead {
    Range {
        start: Box<Expr>,
        end: Box<Expr>,
    },
    Expr(Box<Expr>),
}

The head of a for loop (spec 2.4): a half-open integer range (a..b), parsed only here since ranges exist nowhere else in Varyk, or an expression iterated element by element as a Vec. ..= never produces a ForHead::Range: it is V0001, milestone 4.
