> Currently, it is hard for developers to add explanations to functions and
> user-defined functions. Java has annotation feature. We can make function
> system more explored and explained with java annotations.
> h3. Proposal
> A function should have the following annotations
> * function name (string) - optional
> ** If a function is user-defined, this field is ignored.
> ** the function name of user-defined function is given when it is
> registered.
> * synonyms (string []) - optional
> ** If a function is user-defined, this field is ignored.
> ** One or more aliases can be described.
> * description (string)
> ** *one* line explanation for a function
> * detail (string) - optional
> ** more explanations which can be two or more lines
> * example
> ** what are parameters and what is a result.
> Function signatures can be derived from function name, parameters, and return
> types.
