Hi,

In helping kris with the mango package (the log administrator servlet specifically), I came across the need to iterate over the values of an emum:

enum Level {Trace=0, Info, Warn, Error, Fatal, None};

So, I go about coding like so:

for (int i = Logger.Level.min; i < Logger.Level.max + 1; i++)
{
... //do stuff here with Level[i]
}

Why not add the ability to foreach, so that iteration is nicer:

foreach(Level l; Level)
{
... //do stuff with l
{

Wouldn't you just love to handle enums like this.  I believe iteration over enums is a pretty common thing.

Thanks

That would be nice.

I can't immediately see a problem with it. As long as none transpires, count my vote.

I've never had a need to iterate over an enum, but I agree that it's a nice feature.  Unless there's some bizarre consequence I haven't thought of it has my vote.

I think that a shortened syntax would reduce the redundancy :)

How about:

foreach(Level l)
{
...
}

That way a single argument would have to be an Enum.
