Slightly off topic.
But is there any way to enhance google groups so that it will support
Markdown?
Or at least provides a simple way to post formatted code without the

People often want post code snippets on this group.

Hello fellow gophers,
Ian announced the intention to update how type switches work in the
generics proposal in a golang-nuts thread from this August:

It included this from Ian (which is a snippet of his item #4 from his first

I don't believe anyone is talking about not handling errors. There are
functions that perform a sequence of actions and need to go no further when
an error is encountered. An example of this type of function is presented
in the "Errors are Values" post:

Neat. What you and I are doing is very similar. Particularly how the
handler is "bound" to the error and checks to make sure that the error is
non-nil before attempting to recover.
The differences I see in our approaches are as follows:
I support wrapping an error or performing some arbitrary
Some developers build sheds others build skyscrapers. Exceptions let you build
skyscrapers - but not everyone needs a skyscraper.
I’ve use both methods extensively in my career - well written exception code is
far easier to write and maintain for more complex systems.

I consider checked vs unchecked exceptions “well written” or even valid code.
Checked exceptions are similar to Gos error return except more/easier/better?
compile and coding time validation. Unchecked exceptions are similar to panic
recover except you have more information.
There is no

The code is almost trivial. It consists of two small functions,
I'm referring to errors found in the function (i.e., by calling
other functions). It's the responsibility of the callers of a function to
handle the errors it returns, and not the function itself. How can one
function claim responsibility for the error handling strategy of all
programs using it?

Can you clarify what you mean mean by “the code does exactly what it shows on
the page”? How do you know by looking at the code, or even compiling the code,
that all possible errors returned by a function are handled? That to me is
biggest difficult in reading (or using) others Go code.
Roger beat me to it.
But allow me to rephrase,

clear method of error handling despite it being a major concern of folks
who don't use Go much." *

I am writing this to see what everyone thinks about a solution I have for
the composite pattern.
The composite pattern is when 0 or more instances of some interface X can
act together as a single instance of interface X. For instance you may have
a Filter interface that filters instances of

Many, many thanks. The hpcloud/tail hit the spot exactly, along with using
timer.AfterFunc() along with judicious use of .Stop() calls to

4. Your matrix multiplication is just a few CPU instructions, it is hard
to measure something tiny reliable. So use larger matrixes.
5. You are benchmarking also how fast you can format and output

1. Do not use go run main.go. Never!
2. Do not run your code with the much less problematic go run because
go run compiles and executes your code and the time needed to compile
it will ruin all benchmarks.
3. Always use the benchmarking infrastructure built into go test and

Suppose I am writing a package that is in its own module, and I want

Before modules, I would develop the package in ~/go/src, write the
test program somewhere else, and import the package.
