some related links:

• Syntex failed to build on nightly channel serde-deprecated/syntex#117
• hr_lifetime_in_assoc_type future-compatibility warnings rust-lang/rust#33685

environment:

• rustc 1.17.0 (56124baa9 2017-04-24)

summary:

• a recent change in rust-lang makes previously valid syntax throw an error
• syntex_syntax isn't currently being maintened

what's a good version of rust to install that won't throw this error?

has anybody patched syntex_syntax to work properly?

update:

• I'll include excerpts from a bash script that includes lots of notes
• the short version is simply that:
  • rust v1.17.0 introduced the issue
  • rust v1.16.0 works fine

@warren-bank: yes, I agree, this is only an issue with rust v1.17.0. Updating to the latest ethcore will fix this openethereum/parity-ethereum#4983
