Go - can someone explain why empty interfaces can hold any value, where it seems "regular" interfaces only define functions? In other words, why can the empty interface hold something other than a function definition?
new to Go and interfaces in general...

Interfaces constrain the values they contain to values whose type implements at least the methods specified in the interface.
The empty interface specifies no methods, so a value of any type satisfies it: they all implement at least no methods.

I guess that makes sense. I first saw this when reading about using an interface as a value in a map for json.
