Hello,
_arguments -s : '*-r=::->file:*:::->test'
does exactly what the manual say it does, IOW all the remaining words on
the line are to be completed as described by the action. That's not what
I want, though: the whole (-r file 1*test) can be repeated, and I'd like
it to offer also -r.
Can _arguments do this for me somehow, or is this up to me?
Hints appreciated.

Thought I might be more specific.
I have the following command (ABNF with implied whitespace at
obvious places):
cmdline = "tence" ["-h"] *("-i" dirlist) 1*("-r" file 1*(test))
and this completion function:
-------------------------
#compdef tence
local context line state
typeset -A opt_args
_arguments -s : \
{-h,--help} \
'*'{-i,--include-path}'=:include_path:->incpath' \
'*'{-r,--run}'=:file:->testfile:*::class:->testclass'
case $state in
incpath)
_dir_list && return 0
;;
testfile)
_files -g '*(.)' && return 0
;;
testclass)
# offer tests defined by this file for completion
local -a tests
tests=($(_call_program tests tence -C $words[1]))
compadd "$@" -a tests && return 0
;;
esac
return 1
-------------------------
with "mycmd -r F a b c <CURSOR>" on the command line, completion
should offer not only further tests (d e f), but "-r" as well.
I don't want to pollute the interface with dummy arguments to halt
the class optarg processing on, and also would love to defer as much
as possible work to the standard functions.
_arguments is already there, I don't want to write another parser.

Generally two colons together mean special things. It should work if
there's at least a space, otherwise it's certainly a bug.

Yes, that's a real nuisance in working out what's going on.

You need to manipulate curcontext. The usual idiom is
local curcontext="${curcontext}:extra:bits"
or something.

No, I passed on the mail to the list (and this one, too).
