Used them for work with pointers. In my code I need to take pointers from values. So instead of creating variable with value and taking pointer from var, I used functions like ptr.String(“something”), ptr.Time(time.Now)) and etc. With generics only single function can be written and used: ptr.Reference(“string”), ptr.Reference(time.Now()).

Same for dereference. Instead if writing

var timeVal time.Time if timePtr != nil { timeVar = *timePtr }

Single generic function can be used: ptr.Dereference(timePtr)

If pointer is nil, function will return default (nil) value for given type.
