• Paolo Invernizzi (9/9) Aug 08 2010 Hi all,
• Simen kjaeraas (6/14) Aug 08 2010 There is a bug in DMD in which string literals are lvalues[1].

Paolo Invernizzi <arathorn fastwebnet.it> writes:

Hi all,
On page 273 of TDPL, we have:

enum euler = 2.78;
euler = 2.73 // Error! Cannot modify enum value!

But with D 2.047 I can do:

enum greet = "Hello";
greet = "Ciao"; // Ok?

So the question is, enumerated values are constant?
Cheers, Paolo

That is the problem you here have run into.
