Hi all,

i want to declare an invariant interger, for instance "invariant int x = 3;".
But i've got this error while compiling.

Error: constant 3 is not an lvalue

could someone explain me what's wrong here ? I'm using dmd 2.030

Not sure the following code works for me.

invariant int x = 3;
void main() {
}

And now it's better to start using "immutable" instead of "invariant" that is
probably deprecated. I guess "invariant" will be removed in some time.

Why would invariant be deprecated before there's any documentation on 
the meaning of immutable?

Stewart, you've been here for years.  I *know* that you know that the
D documentation is often incomplete or incorrect.  You're acting like
you don't ;)

I don't know, the numerous comments and bugzilla reports about how
lacking you feel the spec - and the quality of its spelling - is?

That might have something to do with your first two sentences, but I'm 
still lost for where you got the third from.

"Why would invariant be deprecated before there's any documentation on
the meaning of immutable?"

Because the docs are usually out of sync with the compiler (which you
know) and because features and changes fall out of the sky with no
prior indication (which you also know)?
