## Functions
template<typename Types, typename UnaryOp>
GIL_FORCEINLINE UnaryOp::result_type | apply_operation (variant< Types > &arg, UnaryOp op)
| Invokes a generic mutable operation (represented as a unary function object) on a variant.
template<typename Types, typename UnaryOp>
GIL_FORCEINLINE UnaryOp::result_type | apply_operation (const variant< Types > &arg, UnaryOp op)
| Invokes a generic constant operation (represented as a unary function object) on a variant.
template<typename Types1, typename Types2, typename BinaryOp>
GIL_FORCEINLINE BinaryOp::result_type | apply_operation (const variant< Types1 > &arg1, const variant< Types2 > &arg2, BinaryOp op)
| Invokes a generic constant operation (represented as a binary function object) on two variants.
