Suppose I've wrapped a Variant in a struct/class which ensures

Is there a way to call a function (ex: popFront) on the
Variant, *without* knowing ahead of time all the possible
static types it might might contain?
You are basically reinventing OOP here.
Instead of Variants, use objects that implement an interface
(e.g., `std.range.interfaces.InputRange`). Then you can call
methods that belong to that interface and rely on virtual method
dispatch to choose the correct implementation at runtime.
