ICE on nightly

[LukasKalbertodt]

Not really a problem with solicit itself, but I thought it's worth mentioning. Compiling with the current nightly compiler (rustc 1.3.0-nightly (6d71ce536 2015-07-06)) causes an internal compiler error. This means that every project that somehow needs solicit (or hyper for that matter) fails to compile.

The corresponding rustc issue is probably this (although its much older): rust-lang/rust#24520

Output:

   Compiling solicit v0.4.0

note: the compiler unexpectedly panicked. this is a bug.

Could not compile `solicit`.

Thanks for the heads up...

I noticed this yesterday too and apparently it should already be fixed by rust-lang/rust#26807, which is in the new nightly (rustc 1.3.0-nightly (e6a9be10b 2015-07-07)).
