Better?

Perfect! Do you think it is a good idea to also allow an IO as
argument to foreach so we can save a block?

FCSV($stdin) { |csv_in| csv_in.each { |row| p row } } # from
$stdin

would become

FCSV.foreach($stdin) { |row| p row } # from $stdin

Kind regards

$stderr
+1
would become

FCSV.foreach($stdin) { |row| p row } # from $stdin

Btw, this inspired me to Toy example of simpler loop nesting · GitHub

I would rather not go that far. The standard CSV library for Ruby 1.8
varied its interface slightly from the IO methods I assumed it meant to
imitate. For example, open() was essentially foreach() when you passed
an “r” mode. This always bothered me.

We don’t need two blocks though. I showed it that way in the
documentation for consistency (to hopefully make it easier to remember),
but this works:

$ echo -e ‘a,b,c’ | ruby -rubygems -e ‘require “faster_csv”;
FCSV($stdin).each { |row| p row }’
[“a”, “b”, “c”]

Good point. Thank you for consideration of my suggestion.

Kind regards
