new `crate` keyword breaks derive

[kazcw]

This panics ("failed to parse derive input"):

#[derive(Fail)]                                                                                                  
crate struct Foo;

This works:

#[derive(Fail)]                                                                                                  
pub(crate) struct Foo;

I believe the fix will be to upgrade to a newer version of Syn which supports this newer syntax.

This has become more relevant now with the recent call to arms to test the module system changes

[ExpHP]

Ah, I think I see what's going on. This has been fixed, but the fix is not released because the next planned update to 0.1.X was to have it use a compatibility shim over 1.0.0 (which got delayed).

This is a shame; perhaps some recent fixes like this one should be backported onto something more closely resembling the 0.1.1 release.

@mitsuhiko was curious, do you know if there's a plan for releasing failure 0.1.2 with a fix like this?

[mitsuhiko]

@alexcrichton yes, but i do not yet have rights to crates.io

[mitsuhiko]

I'm going to see if I can downgrade the current master so it does not need the 1.0 version, otherwise I might just fork it off from an older revision for now.

[alexcrichton]

@withoutboats ping on this, mind giving @mitsuhiko publish rights?

[mitsuhiko]

There is a pending release in #229 now. I need to do a lot of testing though (ideally a crater run but I do not know how to achieve that) as it's a merged version of 0.1 and 1.0.

[mitsuhiko]

This is fixed on master. I'm going to close this issue for now.
