What does this syntax mean?

Is there some way of using it to immediately access the info node
referred to?
M-: (info "(viper) Top")

Great, thanks. That is useful to know.

"(viper) Top" still seems like a pretty weird syntax. Just out of
curiosity, is there some explanation? I see that the shell version is
'info filename nodename'. And according to wikipedia info was written
for GNU/linux. So it's a post-linux emacs design? Wouldn't

(info filename &optional nodename)

have been more natural?


This is essentially what it is. Try C-h f info and you read:

info is an interactive compiled Lisp function in `info.el'.
It is bound to C-h i, <f1> i, <help> i.
(info &optional FILE-OR-NODE BUFFER)

Enter Info, the documentation browser.
Optional argument FILE-OR-NODE specifies the file to examine;
the default is the top-level directory of Info.
Called from a program, FILE-OR-NODE may specify an Info node of the form
Optional argument BUFFER specifies the Info buffer name;
the default buffer name is *info*.  If BUFFER exists,
just switch to BUFFER.  Otherwise, create a new buffer
with the top-level Info directory.
