This is not something that I've thought about before, but the behaviour
of math.Max when only one of its arguments is NaN does not agree with
the C convention or the IEEE-754 standard behaviour for max (5.3.1 p19

bzip2 compression is not trivial so making sure the review catches any
issues will take time. Finding people with the relevant expertise and
the time to do the review is not necessarily easy.

I would like to be able to obtain the original type for an alias given
a source input. I can see in "go/types" that it's possible to know
whether a named type is an alias by `typ.Obj().IsAlias()`, but I cannot
see how to obtain the actual original type unless it is an alias for a
basic type.

I just noticed today that the io.Closer docs say that "The behavior of
Close after the first call is undefined. Specific implementations may

Should this be "unspecified" rather than "undefined"?

You can use the garble tool[1] to strip/garble things like this.
$ cd golang.org/x/tools/cmd/stringer
$ garble build .
$ go version -m stringer

You can use len to determine the sizeof a struct.

Sorry. That was a joke. You asked why you can't use len(); you can, by
using it to it into create something that is indexable (and so a
possible parameter for len()).

While not a tool, there is code that can be bent to this in

information for a tool to obtain homepage and issue page links from Go

I have thoughts about the impact of assertion libraries in software
engineering. I came from a background where they are commonplace into
Go and in my earlier projects I used some the earlier iterations on
them (go-check).
