metadata.RemoteAddress()is implemented withnet.JoinHostPort:https://github.com/MetaCubeX/Clash.Meta/blob/fdd327d58da49b0bf21b0908bc7e3d475eae63a3/constant/metadata.go#L154-L157
However, most use cases of
RemoteAddress()is passing it toM.ParseSocksaddr, which is implemented withnet.SplitHostPorthttps://github.com/MetaCubeX/sing/blob/f9766a597f7dbd6919a9b60c1eb1e41221e3ab1d/common/metadata/addr.go#L186-L195
Those redundant string concatenations can be ruled out by making use of
M.ParseSocksaddrHostPort.
