I get an extremely confusing error (see title) for a short line of code: `f((a -> a,); b=1)`. Not sure, what is wrong here? I tried adding another set of parentheses, but the same error: `f(((a -> a),); b=1)`.

Well, this just means it doesn’t reproduce for you. I get the error quoted in the topic title:

```julia

julia> f((a -> a,); b=1)
ERROR: syntax: ssavalue with no def

```

Same in IJulia, for example, and with `startup-file=no` as well.

Fair point in this case. Rebuild/redownload Julia and see if it still occurs.

Can reproduce on Julia 1.1.0, but not on Julia master.

Please open an issue on Github.
