Is Anonymous Interface Implementation Possible in Go?

The ability to define an anonymous implementation of an interface using anonymous functions, similar to the pseudo code:

RandomNumOp({
   Binary: func(a,b int) int { return a b},
   Ternary: func(a,b,c int) int {return a b c},
})

is not directly supported in Go. Here are some possible approaches, depending on whether the implementation is required to work:

If Implementation Must Work

• Use an Existing Implementation: Define a type that embeds an existing implementation, providing the required methods.

If Implementation Is Not Required to Work

• Use an Anonymous Struct Literal: Embed the interface type in an anonymous struct literal, providing a placeholder implementation (with empty methods) for the interface functions.
