Not all for loops are created equal.
Consider
for x in [value1, value2, value3]
You would expect to see x vary in the order of the values in the list.
However – if x and the values are of an enumerated type, looping the “list”
does NOT loop in the apparent order of the constant, but in the order of the enumerated type declaration, such as it would for any set.
An example:
The above code yields
Declared: TEnum = (plough, foo, bar, wtf)
Test order: [wtf, plough, bar, foo]
Looping an Enum Set
plough
foo
bar
wtf
Looping an Enum Array
wtf
plough
bar
foo
Press Enter:
This can be easy to miss, so if loop order is important – make sure you code your enums into an actual array and do not leave them as a set.
