Syn rejects some names

[Loïc Hoguin]

Syn doesn't accept some names as the following snippet shows, despite saying it accepts any().

Probably related to #3 and actually sounds like the problem was fixed in the past and is back.

2> application:ensure_all_started(syn).
{ok,[mnesia,syn]}
3> syn:join({stream, {server, <<"hello">>}}, self()).

Can confirm, also tuple like {atom(), map()} not working too.

[Roberto Ostinelli]

Thanks for your reports. I guess you were referring to #6, the issue there was that the match guard function is different for tuples in mnesia:dirty_select/2 (see here).

Will get to it.

[Loïc Hoguin]

Yes, #6, sorry.

[Roberto Ostinelli]

Before I get to this, do you happen to know why the match guard function is different for tuples, and if this has changed in Erlang 19.3?

[Loïc Hoguin]

I have no idea. And for the record, I was using 19.2.

[Loïc Hoguin]

Thanks! We will try it soon and report back.

[Roberto Ostinelli]

I will release it to hex as 1.6.1 asa Travis is green too.

[Roberto Ostinelli]

1.6.1 has been released.
