1/// Strip Go method receiver prefix from a symbol name.
2///
3/// Go struct methods are indexed with a receiver prefix:
4///   `"(*ReceiverType).MethodName"` or `"ReceiverType.MethodName"`
5///
6/// Returns the base name (everything after the last `")."`), or the original
7/// string if no receiver prefix is present.
