That's not necessarily a problem, especially if the struct is
small, passing by value is faster than by reference.
What is your code trying to do?
Can enums be made of classes yet, or is there a way to make
the enum based on structs more efficient?
enums can't be classes, but you could make a static class
constructed at compile time and pass that reference around.
Hmmm... What do you think the crossover point is for performance
of value vs reference? ie, how large can a struct be before
passing it around gets slower than passing around a reference?
(I would guess 8 bytes, but that's just a guess).
I am trying to emulate the java enum type. Enums are great for
data
safety in API design. The more immutable data they contain the
better in my opinion - hence my concern about performance.
