it's a variable name for a polymorphic function, taylor series, euler formular, etc. depending on context. This is a significant difference to singular types, but being a variable name to an abstract concept is in principle no different to typesetting x. This goes neatly with "everything is an objectreference" and might be more of a programmer's perspective.
