------- Comment #7 from smjg@iname.com  2009-04-19 07:29 -------
> fog.d(5): semicolon expected, not '}'

This last message is the one that's correct.  A declaration of a variable (which is what test is) always requires a closing semicolon.

What's actually happening is that it's trying to parse
{ struct test2{} }
as a struct initializer.  Nothing to do with the struct that's actually
declared inside.  See for yourself:

----------
C:\Users\Stewart\Documents\Programming\D\Tests\bugs>type bz1030a.d
void main() {
        void delegate() test = {
                struct test2{}
        };
}

C:\Users\Stewart\Documents\Programming\D\Tests\bugs>dmd bz1030a.d
bz1030a.d(4): expression expected, not 'struct'
bz1030a.d(4): comma expected separating field initializers

C:\Users\Stewart\Documents\Programming\D\Tests\bugs>type bz1030b.d
void main() {
        void delegate() test;
        test = {
                struct test2{}
        };
}

C:\Users\Stewart\Documents\Programming\D\Tests\bugs>dmd bz1030b.d

C:\Users\Stewart\Documents\Programming\D\Tests\bugs>
----------

Since AIUI there's no overlap between what's parseable as a struct init and what's parseable as a delegate literal, there should be little or no problem getting it to work.

It behaved exactly the same way in DMD0.175. Another of these annoying cases where we have two unrelated bugs in the same report. It should not have been reopened. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
