error[E0518]: attribute should be applied to function

when installing my mdblog crate with nightly-2018-03-28, all is well,
but with nightly-2018-04-01, compiling error:

$ cargo install mdblog

I get that error in Gutenberg nightly as well. Looks like a regression from rustc? I'll check if there is already an issue for that

[Keats]

I did a cargo update in the tera folder and it compiles? weird

[FuGangqiang]

after cargo update, my crate also compiles.

Most probably related to #218.
