I don't really know what the correct way of doing this is. There 
really ought to be a property .value of enums.

The stringof property will return what you want, although 
annoyingly with quotation marks around it ([1 .. $-1] on the end 
will clear that up of course). For types other than string it 
returns cast(application)value as a string, which is not 
particularly helpful.

BTW this only happens with named enums, anonymous enums print the 
value not the name.


I don't know how much any of this is intended behaviour and how 
much is just by chance.
