property bool GeneralExpression
Determines how string values are interpreted when they are written to a definition table. When True (default), a string is taken to be an expression, which must parse to be a valid expression. When False, a string value is stored as a literal string. For example, the value Pi would be interpreted as the Identifier Pi when GeneralExpression is true, and would thus evaluate to 3.141592654, but the same string would be interpreted as a literal character string when GeneralExpression is false, and would evaluate to two-character textual string.
