FWIW I've started working on autocomplete functionality for rust.

I'm persuing the 'scan the source code text, incrementally parsing relevant
pieces' approach. I'm also learning the language so it's a bit slow going

Perhaps it's not that important that it will be able to continue after
errors? I think that generally there should not be type errors even while
programming is in progress. It means that if I'm referring to something I
have to immediately write a stub for it, but I don't think it's that bad.
Noam
Is it correct for me to assume that, even if accepted, virtual things will
be behind a feature flag for 1.0? If so, then I think that will be enough
friction to cause library authors to favor traits instead, especially if
users of virtual-using-libraries would have to turn on the feature flag as

Hello Rust,
Just wanted to remind everyone of the Rust meetup tonight at the SF Mozilla
Headquarters. Doors open at 7pm. We've had to make some substitutions with
the speakers due to some conflicts, though. Here is the lineup:

The Mountain View office outgrew their old location and they're moving to a
larger one.

Matthieu,
I tried to model something similar this way. Sometimes the extra pattern
matching gets tedious with this approach. You also end up with a lot of
constructors with similar names. I also found myself writing a lot of trivial
function wrappers around constructors. Of course there
Also this approach uses more memory. At least a byte per pointer and maybe
more with padding. In most cases like this you would prefer to use a vtable
instead of tags to reduce the memory footprint.

Hi,
coersion still can break any code depending on library really badly.
Just suppose the method implemented for Hello in the following example
was added later. After the change, different function is called. IMO,
the risks from glob imports are no worse than this.
struct Hello {
s : ~str

A vtable uses memory too. Either it uses a

Yes, but with tags you pay the cost even if Option is None.

I don't think the coercion is much of a problem; at least, not a fixable
one. Dot notation for method syntax in a systems language that supports
values pretty much requires some
A really out there solution to reduce memory may be to use a Cap’n Proto style
arena that uses offsets instead of pointers, but I’m sure there are a lot of
difficult problems with that.

Yup! That's what we call Uniform
Thinking about this a bit more, maybe the memory cost could go away with tagged
pointers. That is easier to do on a 64-bit platform though.

Hi Eric,
Coming back on memory; I presented two designs:
- in the first one, you have a tag at each level of the hierarchy, which
indeed uses more memory for deep hierarchies but means that a type only
knows about its immediate children
- in the second one, you have a tag only at the root of
