Hi Eric, this is an example of code which gives the error :
struct Cls {
vec : ~[~int]
}
/*
Does not compile, yielding error message :
method `index` has an incompatible type for trait:

For one, the Index trait is in dire need of an overhaul.
In respect to the operator traits in general, I have actually been thinking of
submitting an RFC proposing that they take thier parameters by-value instead of
by-ref. That would remove the auto-ref behaviour of the operators which is more

Greetings Rustlers!
Projects such as cargo and Servo have recently expressed interest in having a
breaking changes changelog as part of the rust repository. It's often
difficult for those not closely tied to the compiler itself to keep up with all
the changes that are getting made. Additionally,
Hello all,
I have two somewhat related questions to ask you fine folks. I'm trying to
implement something that selects on a variable number of receivers, which
can change during program execution. I've been attempting to do so by
making Handles to those receivers and storing the handles in a

For this program, the compiler complains at the line with
Ah, yes I failed to see the warning in the documentation. add()ing the
handle after moving it into the hashmap does seem to make things better.
Thanks for your help!
