No. You can only either a) build something on top of it (i.e. a wrapper),
or b) copy the package with your own modifications and distribute that.

[go-nuts] Add to existing Go Package

[Rich]

What I want to do is extend the go standard log package. I am using log to 
write logfiles, but there are two things with it I need to extend. 

The first is a 'Format' string, which allows me to change the time format 
string log uses.

The second is to be able to print to both logfile and stdout., This is 
useful when you're starting your server, and you want some of the output to 
go directly to stdout. I use this so that with one line I can print the 
same line to stdout as I print to my log file.

lgOut.Tprintf("Server Version: %s Started and listens on:  %s:%s, ", 
server.Version, server.Address, server.Port)

That would print to both stdout and to the logfile lgOut is configured for.
Ex: 
20220117-13:45 | Server Version 1.0.1 Started and listens on 127.0.0.1:8080"
 
What I am worried about is that my version of log will diverge from the Go 
standard log package.   Is there a way to extend an existing package so 
that my adds to the log package pulls from whatever happens to be the most 
current version of log?
