in reply to Re: strict refs
in thread strict refs

I use strict; because it helps me avoid writing poor or ambiguous code.

While no-one else has persuaded me to use strict;, the general consensus of opinion, even in the DBI docs, is 

To use DBI, first you need to load the DBI module:

  use DBI;
  use strict;

(The use strict; isn't required but is strongly recommended.)

What I lack at the moment is the knowledge when (and sometimes how) to safely switch it off.

    Strictures are lexically scoped, so if you turn them off in a small block, you are pretty safe.

    This particular example happens in a small foreach loop, so there's your block. If you're in the middle of a longer sequence, you can say 

    do_stuff();
{ no strict 'refs';
    printf "%s=%d\n", $_, &{"DBI::$_"};
}
do_more_stuff();
