45# @numeric: true if the host/port are guaranteed to be numeric,

99#
100# Captures the address of a socket, which could also be a named file descriptor
101#
102# Note: This type is deprecated in favor of SocketAddress.  The
103# difference between SocketAddressLegacy and SocketAddress is that the
104# latter is a flat union rather than a simple union. Flat is nicer
105# because it avoids nesting on the wire, i.e. that form has fewer {}.
