Euphoria Ticket #892: type enum return 1

As a implementation detail, the enum types return which place they were in their declaration. It is better they return 1. This way most enum types can be implemented more efficiently:

Consider this code:

type enum boolean 
     FALSE = 0, 
end type 
boolean k 
? boolean( 5 = 5 ) 

The code generated for the last line is equivalent to:

? find( 5 = 5, { FALSE, TRUE } ) 

This is fine for short lists but for long lists its less efficient than:

temp = 5=5 
? integer(temp) and FALSE<=temp and temp<=TRUE
