unsupported or misplaced expression error

I get this on latest Julia master, both with the released and the master CSV.

julia> VERSION
v"1.1.0-DEV.760"

julia> using CSV

shell> cat /tmp/foo.csv
"foo","bar"
1957,13

julia> CSV.File("/tmp/foo.csv")

On Julia 1.0.2, it works fine.

I am still getting the error on latest master, can anyone please confirm that it is not a quirk peculiar to my setup, but a bug in CSV.jl?

I don't see the same issue on master. It seems like you might have your Parsers.jl package in a bad state. You might try deleting it/removing it and trying to re-install it.

Thanks, did that, didn't help, reported at Parsers.jl
