I finally looked at this.  The documentation says

 With two colons before the message, the words special array and the
 CURRENT special parameter are modified to refer only to the normal
 arguments when the action is executed or evaluated.

I can't see any evidence not being able to complete options thereafter
is deliberate.  This is to do with the restrict_range() calls in
ca_set_data(), I think.  The :: causes the first argument to be
ca_laststate.argbeg instead of ca_laststate.optbeg, which fits the
descxription; I can't see any other intentional effect.  It's possible
there's some miscounting later, or something, but it looks obscure.
