Subject: 24.1.50; HOOK variable name in `add-hook' etc. confusing
Date: Thu, 26 Apr 2012 00:45:26 +0200

Hi,

this is just a tiny detail, but confusing for newbies:

Turn on eldoc mode in any elisp buffer.  If you move point into an
`add-hook' or `remove-hook' form, you get e.g. the message

  remove-hook: (HOOK FUNCTION &optional LOCAL)

You could misinterpret that and think that the first argument must be
a value representing a hook.  But actually it must be a _symbol_
holding a hook.

So, I want to make the suggestion to replace the variable `hook' in
the definition of `remove-hook' by `hook-var', and to do the same for
`add-hook' and `run-hooks'.  Then, the eldoc message would be

  remove-hook: (HOOK-VAR FUNCTION &optional LOCAL)

which is more clear.


Thanks,

Michael.
