void main()
{
string[string] hash;
foreach (i, key, val; hash) // ng
{
}
}
I think it would be nice to support this, it allows for things like:
void main()
{
string[string] hash = ["foo":"1", "bar":"2"];
string res;
foreach (i, key, val; hash) // ng
{
if (i) res ~= ", ";
res ~= key ~ " " ~ val;
}
assert(res == "foo 1, bar 2");
}
A map + joiner call would suffice here of course.
