Thanks, fixed. But curiously it doesn't. You can call it (and I always
do call it) with one argument, as one does in CL.
By the way, the only reason I had to do this (I rarely use this outside
interactive contexts) is to make eldoc.el work in Emacs 26.3. I explain
this in the commit message, but I'm still uncertain of the cause of the
problem:

Fix Eldoc problem when loading on Emacs 26.3
When defining the obsolete variable alias for old
eldoc-documentation-function (which now points to the newer
eldoc-documentation-strategy), one gets the error "don't know how to
make a localized vareiable an alias". I'm not sure, but I suspect
this is because Eldoc is preloaded in Emacs 26.3 and the
eldoc-documentation-function variable is already set locally by some
Elisp buffer.
Uninterning the symbol shortly before defining the alias seems to fix
it.
Separately, I also noticed that calling `package-install` for Eldoc in
Emacs 26.3, will _not_ load eldoc, and neither will `require`. One has
to `load` it specifically, even after calling `package-initialize`.
