Lets not use the abbreviated perl predefined variables, that confuse newbies, and are partly responsible for perl's reputation as a read only language. Instead can I suggest:

use English '-no_match_vars';

sleep 60 if 0 == ($INPUT_LINE_NUMBER % 10)

Or better still:

sleep 60 if 0 == (FILE->input_line_number() %10)
