Fixes #1063
lang.ReferencesInExpr
returns variable references for the number of variable calls. In most cases, this is not a problem, but access to elements of the map also counts as a variable call, so multiple references may be returned for the same variable.This PR avoids returning multiple references to the same variable by returning a map instead of a slice.
