  For demonstration purpose, let's assume that we already have some types and structs describing our data. And we want to implement filtering of data flow, via providing our users to configure such filters via expressions.

 Much better. But using time's package methods isn't pretty. What if we can override operators? And we can! Let's describe another function.
 
 ```go
-func (*Requset) Before(a, b time.Time) bool {
+func (*Request) Before(a, b time.Time) bool {
 	return a.Before(b)
 }
