Can we change the cores handler to a non-anonymous function?

[mnhkahn]

We used gin and this cores package. I found a problem that the cores handler is a anonymous
handler, and this causes a problem that we use the function's to auto statistic api's cost time. Cores handler will show func1, so I'm considering if we can change the function like this:

func New(config Config) gin.HandlerFunc {
	cors := newCors(config)
	return cors.applyCors(c)
}
