in thread One to one file output idiom

maybe try $. to catch the first line per file, like
C:\tmp\files>perl -nE"say qq($.--$ARGV) if $.==1; $.=0 if eof " a b c 1--a 1--b 1--c

Unfortunately I need to reset $. at the end of each file, which is kind of hacky! :/

    Closing ARGV before it gets opened again would be the non hacky thing way to do it since it's shown in the doc, although it's a bit longer.

    Edit: choroba pointed out it was shown in the doc for eof not open
