spurious camel case warning

[jesse99]

Don't have a good repro for this (tho I can get an icky one once I push my project), but when compiling with -W non-camel-case-types I'm getting the following warning:

<intrinsic>:23:4: 115:5 warning: type, variant, or trait must be camel case
<intrinsic>:23     trait ty_visitor {
<intrinsic>:24         fn visit_bot() -> bool;
<intrinsic>:25         fn visit_nil() -> bool;
<intrinsic>:26         fn visit_bool() -> bool;
<intrinsic>:27 
<intrinsic>:28         fn visit_int() -> bool;
               ...

This should be fixed by 7fb1a4e

Fixed, but needs a snapshot to make the warning when compiling with stage0 go away.

I don't see this warning anymore. Closing.
