Hi everyone,

I noticed that, starting from Ruby 2.5, parsing multiple CSV files from ARGF stops after reading first input.

For example, the simple one-liner:

ruby -r csv -e 'CSV.new(ARGF).each{|row| p row}' file1.csv file2.csv

Only processes the content of file1.csv

Could you report this to https://github.com/ruby/csv ?
