try: reconsider func names

I've been using try in scripts and really liking it.

However, I find A0, A1, etc to be fairly unintuitive. Particularly since in the kind of context in which I'm using try, I'm also tempted to dot import it. Then code reads:

A0(fn())

and the A0 is mysterious.

I'm on board for them being short. But maybe E for error? H for handle? X for "danger I might panic"? C for check?

Also, I'd like to request just "A" instead of "A0". :)

ioutil.SectionWriter runtime error:slice bounds out of range

hi ! I'm using the ioutil.SectionWriter to write to files at different offset concurently,but runtime error:slice bounds out of range raised. I'm confused if I used the wrong way?the code I used is as follows:

sectionWriter:=ioutil.NewSectionWriter(file,offset,num)
_,err=io.Copy(sectionWriter,resp.Body)

the error is as follows:

panic: runtime error: slice bounds out of range

goroutine 20 [running]:
panic(0x80f5a0, 0xc82001a0e0)
        /usr/lib/go-1.6/src/runtime/panic.go:481 +0x3e6

        /usr/lib/go-1.6/src/io/io.go:350 +0x64

During the debug,I find that when the error happens,the cnt is much larger than the length of data slice.But I don't know how to solve it !Am I using it the wrong way?

memfile: add empty Close function

Sometimes it's useful to have also Close() function in memfile. I needed it when I worked with https://github.com/faiface/beep

Just something simple like this:

func (fb *File) Close() error { return nil }

Can you please add it?

break out try into its own repo?

Repos are cheap, and try is useful. :)
