I am compiling my own code using Go 1.17.5 (also happens w/ other versions)
When I compile this code on my computer running win 10 21H1 64-bit
system using "go install", the resulting exe file bothers windows
anti-virus a lot. This is what I see

NewThing[int, int]() returns a map[int]int, and therefore that's the type
of MySet in func runInt.
You can think of NewThing[T1, T2] as a family of functions, like
func NewThing_int_int() map[int]int { ... }
func NewThing_int_byteslice() map[int][]byte { ... }
... etc

MONOVANIA[0] was created for the Metroidvania Month 14 game jam.[1] Its
source code is freely available.[2]
Players start the game with the ability to rewind time.
The objective of MONOVANIA is to collect the three exit keys and make your
gray-t escape.
What is a Metroidvania video game?

This is perhaps pedantic, but the two meanings are not incompatible.

Have you ever heard of a Pomodoro technique? It helps stay in the flow
and focused even when activities are overwhelming. We believe that everyone
has it's own time management style and it's just a matter of time to find a
right tracker. Maybe a better idea, to write a new one!

Jan, assuming you're running on an AMD CPU, this is go.dev/issue/34988 (if
you're not running on an AMD CPU, that would be very interesting to know!)
The TL;DR is that this appears to be a kernel bug, and we have a C
reproducer, but we do not yet have a fix or a workaround.

Yes! If you see the release email, there's some steps included:
If you have Go installed already, the easiest way to try go1.18beta1
is by using the go command:
$ go install golang.org/dl/go1.18beta1@latest
$ go1.18beta1 download

Yes, see instructions on how to download/install go1.18beta1. It
explicitly suggests a way that will allow this.

Is there a way to have multiple versions of go installed on the same

You received this message because you are subscribed to the
when writing type parameterized code, it has to work with anything that

concrete type

but when you use it, the type is always known,
A function which takes a value of an interface type, and a function which
takes a value of a constrained generic type, are certainly two different
things.
In the first case, it gets a dynamic boxed value which at runtime may
contain a value of any type that implements that interface - or no
Hello folks,
I've stumbled over a thing and I don't understand if what I've found is
intentionally possible by design...

Why can I compare int with == when it was instantiated from the "any" type
parameter?
The origin of my question is my

This was asked 15 hours ago in the thread with the subject line "Go 1.18
beta1: Embedding Type Parameter in struct definition is an error". :-)

I just learned that type constraints, which are defined as interfaces are
actually not usable in all the places "normal" interfaces can be used in.
E.g., why can a constraint interface not be uses as a struct type?
Let's say I have the func `func Smallest[T constraints.Ordered](s []T) T`.
