      Create a new header src/mongo/db/exec/expression/evaluate.h and define a namespace mongo::exec::expression with a set of functions

      Value evaluate(const ExpressionArray& expr, const Document& root, Variables* variables)

      one for each

      • ExpressionArray
      • ExpressionArrayElemAt
      • ExpressionFirst
      • ExpressionLast
      • ExpressionObjectToArray
      • ExpressionArrayToObject
      • ExpressionConcatArrays
      • ExpressionIndexOfArray
      • ExpressionIsArray
      • ExpressionReverseArray
      • ExpressionSortArray
      • ExpressionSetDifference
      • ExpressionSetEquals
      • ExpressionSetIntersection
      • ExpressionSetIsSubset
      • ExpressionSetUnion
      • ExpressionSlice
      • ExpressionSize
      • ExpressionZip

      The body of the functions will be in a src/mongo/db/exec/expression/evaluate_array.cpp and will be taken from the evaluate() method, and the evaluate() method will be changed so that it calls the new method.
