Bin(&'a BinExpr<'a>)

Assign(&'a AssignExpr<'a>)

Member(&'a MemberExpr<'a>)

A member expression. If computed is true, the node corresponds to a computed (a[b]) member expression and property is an Expression. If computed is false, the node corresponds to a static (a.b) member expression and property is an Identifier.
