// Const Attribute example from manual (http://www.prowiki.org/wiki4d/wiki.cgi?LanguageSpecification/Original)

const int foo = 7;

const
{ // Line 183
double bar = foo + 6;
}

// test.d(183): basic type expected, not {
// test.d(183): no identifier for declarator int
// test.d(183): semicolon expected, not '{'
// --- errorlevel 1


Is the const { } syntax not yet implemented in dmd 0.118, or did I miss something?

Not confirmed. dmd 0.118 compiles the example lines.

Could it be that I am doing something wrong with the compile options?

dmd -c -w -O -release -inline -I. test.d

posting a complete example would help. It works fine for me, too, no matter what options I throw at the compiler.

Right, I had the example running with several other examples as well, now I placed the example in a seperat file:

consttest.d
<code>
import std.c.stdio;

int main (char[][] args)
{
// Const Attribute example from manual
const int foo = 7;

const
{							// Line 10
double bar = foo + 6;
}

return 0;
}
</code>

I still get the same error in line 10 though:

>dmd consttest.d
consttest.d(10): basic type expected, not {
consttest.d(10): no identifier for declarator int
consttest.d(10): semicolon expected, not '{'

Hope that helps.

you can use const with D?

(dmd .118 linux)
I get the same errors. Why not just use
const double bar = foo + 6;

/me (dmd .118 windows)

Actually I don't really have a problem with the above, just surprised my that the compile test failed. Well at least on my setup.

Yes, just not in all the ways that you can in C++.  C++ allows you to, for example, declare function parameters as const, thus making them unmodifyable.  D doesn't.  However, const variable declarations are allowed.

Yes.  That the code snippet on that page isn't within a function.  The attribute { ... } syntax applies at only module or class/struct/union level.

But there does seem to be something missing from the spec here....
