/** Write to a @b `DynamicBuffer`.

    This function appends the serialized representation of each provided
    argument into the dynamic buffer. It is capable of converting the
    following types of arguments:

    @li `boost::asio::const_buffer`

    @li `boost::asio::mutable_buffer`

    @li A type meeting the requirements of @b `ConvertibleToConstBuffer`

    @li A type meeting the requirements of @b `ConstBufferSequence`

    @li A type meeting the requirements of @b `MutableBufferSequence`

    For all types not listed above, the function will invoke
    `boost::lexical_cast` on the argument in an attempt to convert to
    a string, which is then appended to the dynamic buffer.

    When this function serializes numbers, it converts them to
    their text representation as if by a call to `std::to_string`.

    @param dynabuf The dynamic buffer to write to.

    @param args A list of one or more arguments to write.

    @throws unspecified Any exceptions thrown by `boost::lexical_cast`.

    @note This function participates in overload resolution only if
    the `dynabuf` parameter meets the requirements of @b `DynamicBuffer`.
