How do I fix it?


Unfortunately, this is currently not supported. You'll have to 
use an else-clause to handle the case when the condition is 
false.

It was mentioned in DIP1010, but that bit hasn't been accepted 
yet:

continue in static foreach

[Marc via Digitalmars-d-learn]

How do I use?


static foreach(enum string member; members) {
static if(isFunction!(__traits(getMember, C, m ember))) 
{
continue;
}


give error:


must use labeled continue within static foreach


then I tried:


outer:static foreach(enum string member; members) {
static if(isFunction!(__traits(getMember, C, > 
member))) {
continue outer;
}


give error:


Error: enclosing label outer for continue not found


How do I fix it?
