INTERNAL: A ListExpressionOperator is used with an ArgumentListFunctionExpression. It is capable of expanding the number of arguments it can be an operator for. It is built from a set of start strings, a repeating set of separators and a set of termination strings It typically represents a database function that has a variable list of arguments e.g. COALESCE(arg1, arg2, arg3, .... argn) In the example above "COALESCE(" is the start string, "," is the separator and ")" is the end string @see ArgumentListFunctionExpression @see Expression.coalesece() @author tware
