Change os.Error convention:
...
echo back context of call in error if likely to be useful.
For example, if os.Open("/etc/passwd", os.O_RDONLY)
fails with syscall.EPERM, it returns as the os.Error
&PathError{
Op: "open",
Path: "/etc/passwd"
Error: os.EPERM
}
which formats as
open /etc/passwd: permission denied

code changes for array conversion.
...
as a reminder, the old conversion
was that you could write
var arr [10]byte;
var slice []byte;
slice = arr;
but now you have to write
slice = &arr;
the change eliminates an implicit &, so that
the only implicit &s left are in the . operator
and in string(arr).
also, removed utf8.EncodeRuneToString
in favor of string(rune).
