TIL, implement this when using struct embedding to reference the outer struct from the inner struct. Saw it from tidb

type Gugu interface {
     IsGezi()
}

type baseGugu struct {
    self Gugu
}

func (b *baseGugu) bla() {
   return b.self.bla() + 'base'
}

type Gaocegege struct{
   baseGugu
}

func NewGaocegege() Gugu {
    g := &Gaocegege{}
    b := &baseGugu{self: g}
   g.baseGugu = b
   return g
}

TIL type of go struct is Named instead of Struct, which is why Struct in types package does not contains package and name for itself.

package gu

// the name cece and package gu is contained in Named, while Struct is Underlying
type Cece struct {
     NotCai bool
}
