--
-- Remote meta-variables are meta-variables originating in other
-- modules. These meta-variables are always instantiated. We do not
-- retain all the information about a local meta-variable when
-- creating an interface:
--
-- * The 'mvPriority' field is not needed, because the meta-variable
--   cannot be instantiated.
-- * The 'mvFrozen' field is not needed, because there is no point in
--   freezing instantiated meta-variables.
-- * The 'mvListeners' field is not needed, because no meta-variable
--   should be listening to this one.
-- * The 'mvTwin' field is not needed, because the meta-variable has
--   already been instantiated.
-- * The 'mvPermutation' is currently removed, but could be retained
--   if it turns out to be useful for something.
-- * The only part of the 'mvInfo' field that is kept is the
--   'miModality' field. The 'miMetaOccursCheck' and 'miGeneralizable'
--   fields are omitted, because the meta-variable has already been
--   instantiated. The 'Range' that is part of the 'miClosRange' field
--   and the 'miNameSuggestion' field are omitted because instantiated
--   meta-variables are typically not presented to users. Finally the
--   'Closure' part of the 'miClosRange' field is omitted because it
--   can be large (at least if we ignore potential sharing).

-- performance of the profiling executable [1], and reduces the time
-- attributed to bind from over 90% to about 25%.
--
-- [1] When compiled with -auto-all and run with -p: roughly 750%
