very thanks , I am unfamiliar with the cpu *out-of-order execution ,
but I doubt if my three line code is related ,it will reorder it ??*

A map is basically a pointer to a complex data structure. Setting a
value in a map changes that data structure. If one goroutine is
reading from the data structure while a different goroutine is writing

It is procedural programming with OO seasoning and there's nothing wrong
with that for small projects and utilities. Would like to see some case
studies on using Go on projects with exceptional large code bases. I really
think the all tenants of OOP (encapsulation, inheritance and polymorphism)
That's not up to you to judge if some comment is "harmless" or not. Because
you're not the person the comment has been directed at. Something that

Yeah, I figured this out after some reading.
Some resources explains it might be possible to work with letsencrypr for

A, thanks a lot for your help and sorry for trivial question.
To test the type assertion I should use following code:
printerImpl, ok := p.(*printer.Printer)
if !ok {
panic("wrong type")
}
(*printerImpl).Print("test")
I was trying to call the 'Print' func as *printerImpl.Print("test") no

Hi,
I have a setup where I first generate binary and then run the binary
for the test cases. I was able to do that successfully for basic things,
but when I want to pass the coverpkg flag to the binary it doesn't work as
it is not defined. I can see only coverprofile is defined while cover

I probably do not understand the goal correctly, but: If the user can do
