*tls.Conn does not have a UnderlyingConn() to access the *net.Conn via an exported identifier

[andrewhodel]

What version of Go are you using (go version)?

$ go version
go version go1.17.6 darwin/amd64

Does this issue reproduce with the latest release?

What operating system and processor architecture are you using (go env)?

What did you do?

I need to access the underlying connection of a *tls.Conn exported identifier, but there is no UPPERCASE function to return it.

What did you expect to see?

I expected to be able to access the *net.Conn of a *tls.Conn to modify it, keep alive can be modified after creation.

What did you see instead?

The lack of an error explaining that an identifier is printed with "%+v" but not accessible and a uninformative error when attempted.

Dup of #29257, a Conn.NetConn method was added and it will be in go1.18

Also, the gorilla websocket library that is looking for a new maintainer has a function, conn.UnderlyingConn() that does the same thing to provide access to the *tls.Conn.conn object. Might want to work with them on naming. Andrew
