Syntax error with Reason files and uncaught exceptions

[Lupus]

Using ppx_expect v0.13.0, ppxlib 0.12.0, when exception happens in a test, ppx_expect generates invalid attribute:

[@@expect.uncaught_exn {|                                                                                                                                                   
.....
|}];

In Reason all attributes use single @ symbol.

The logic writing the corrected file (in https://github.com/janestreet/ppx_expect/blob/master/matcher/matcher.ml) would need to be adjusted for reason files

@Lupus, happy to accept a patch to support reason.

@Lupus have you figured this out?

[Lupus]

Well, I just avoid promoting test runs that ended up with exceptions. Last time I did it just so that I can read it in IDE fully instead of looking at diff in the terminal, and them I ended up with Reason being unavailable to parse it back. Git helped me clear this out, not a big deal :)

explains how the code otherwise compiles. Thanks.
