The 9th commandment settles this IMO: "Where D code looks the same as C code, have it either behave the same or issue an error."

Compiles without error, but fails in D.

==============

int i = 1;

void main()
{
label:
    {
        int i = 2;
    }
    assert(i == 1);
}

==============

I've been porting a fairly large C++ codebase to D (the D frontend) and this seems to be a fairly pointless gotcha.

Open an enhancement if you want something else, this issue is fixed. Where can I read a more up-to-date version of the spec than what is on dlang.org? And why has the 'spec' keyword been removed, even though the anomaly in the spec was part of the issue? -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
