Macros stripped by quasi_codegen::expand

[jdub]

Hi there,

I'm in the process of updating servo/rust-bindgen's aster/quasi/syntæx stack to the latest releases from *mumble* 0.28/0.20/0.44 respectively.

Using the new versions, some key context-sensitive macros are stripped during expansion -- is this a bug, or an intentional change?

You can see the chatter about this problem on servo/rust-bindgen#270, including an example of the before/after expansion and stripped macro.

Thanks, Jeff

@oli-obk Thanks for letting me know! Should I close this one? I'm not clear on which is the correct repo.

neither am I, just leave it open, we'll close it together with the other issue

FWIW, since servo has upgraded their syntex dependency to 0.50, and for integrating rust-bindgen into servo, we need to have matched version, we have worked around this issue by removing all macro_rules! in files which would be processed by quasi in servo/rust-bindgen#329.
