proposal: crypto/tls: add DialWithConn(conn net.Conn, timeout time.Duration, addr string, config *Config) (*Conn, error)

[mei-rune]

I need build a tls conn on the windows namepipe, but DialWithDialer is insufflcient, becase net.Dialer isnot a interface， I cannot replace it with my Dialer.

similar， I run tls conn on other conn also, like serial port ...

Here is a workaround:
From the source code of DialWithDialer https://golang.org/src/crypto/tls/tls.go?s=3677:3769#L98
You can write DialWithConn outside the package crypto/tls with tls.Client .

Indeed, this is an edge case, and should be handled by dialing your own connection, and then wrapping it with tls.Client.
