This is primarily to make it easier to "hand-over" completion/hover/etc. between different expression types (which do not /need to/ have access to all of
PathDecoder
) and reduce diff conflicts between upcoming PRs where each involves different expression type.It is expected that all complex types (list, set, tuple, map, object) may contain either
Reference
(hence needReferenceTargets
) orAnyExpression
(hence need futureFunctionsMap
and possiblyReferenceTargets
too).I have briefly considered creating a separate type, e.g.
ExpressionContext
or pass these things viacontext.Context
, or use the staticnewExpression()
in all places where(*PathDecoder) newExpression()
is now used, but concluded that it would all be premature optimization at this point.
