I apologize, pure alone wouldn't be enough to cause a compiler error. I  
was thinking of the fact that DMD could/does error on expressions which do  
nothing. However, pure wouldn't be enough to let the compiler know  
'seconds = 5' does nothing. It would probably take a combination of  
const/immutable + pure + nothrow, for DMD to detect that s.seconds = 5  
could not possible produce useful work, and therefore should error.
