In Jade we often have integer constants that are merely used as a unique identifier. e.g.
CustomerType_Personal = 1; CustomerType_Prospect = 2; CustomerType_Business = 3.
If we have a value to add we require to sort constant values by number, then add 1 to the latest one. Which leaves a bit reliance on human eyes being fresh, especially when there is a class with hundreds of constants. I recall adding a value of over 1100 the other day.
Most 3GLs handle this using enumerations. You specify a group and then add in the constant names without a value, or define the first value if required. Google search enum for more information.
Can enumerations be made available in Jade?
