Has the name "polymorphic_value" been bike-shedded already?

It's a good name in principle, but not good from a usability point of view; 
too long, too hard to type without errors in the absence of autocompletion.

- poly_value?
- any_value?
- basic_any?

Also,

- poly

seems to be popular, but it's probably too short.
