Unexpected use of alias in enums (tip)

I wanted to do something like this

Code
type
TMyType = ( Fred, Joe, Bill, Billy = Bill, Mike );


but the compiler expects numbers after the equals.

Now of course I know I could count the bits and put

Code
type
TMyType = ( Fred, Joe, Bill, Billy = 2, Mike );


but that is not very nice (for lots of reasons). But I tried

Code
type
TMyType = ( Fred, Joe, Bill, Mike );

alias
  Billy = Bill;


and it seems to work, so I thought I would share...
