##### make_set

###### Description

Create a `set` from one or more values.

###### Synopsis

    template <typename T0, typename T1,... typename TN>
    typename result_of::make_set<T0, T1,... TN>::type
    make_set(T0 const& x0, T1 const& x1... TN const& xN);

The variadic function accepts `0` to `FUSION_MAX_SET_SIZE` elements, where `FUSION_MAX_SET_SIZE` is a user definable predefined maximum that defaults to `10`. You may define the preprocessor constant `FUSION_MAX_SET_SIZE` before including any Fusion header to change the default. Example:

    #define FUSION_MAX_SET_SIZE 20

###### Parameters

Parameter | Requirement | Description
--- | --- | ---
`x0, x1,... xN` | Instances of `T0, T1,... TN` | The arguments to `make_set`

###### Expression Semantics

    make_set(x0, x1,... xN);

Return type: `result_of::make_set``<T0, T1,... TN>::type`

Semantics: Create a `set` from `x0, x1,... xN`.

Precondition: There may be no duplicate key types.
