Pascal lets you have a bitwise set from an enum using

Set of ENUMTYPE

There's another bug report requesting a to_string () method for the 
enums that will be nice to have too

I was also thinking on implementing a enumflags keyword that acts like 
enum, but shift bits instead of increasing the value. so you can do:

enumflag Mode {
  READ
  WRITE
}

MyOpen (Mode.READ | Mode.WRITE);

What do you think about adding this new keyword? The thing will be good 
when using bitflags so you dont have to use an enum hardcoding the 
values in a manual way:

 enum Mode {
READ=1,
WRITE=2
..4, 8, 16, 32...
}
