Re: subroutine ref while "strict refs"

[ikegami]

my %checkers =
   map {; no strict 'refs'; $_ => \&$_ }
      qw( check_char check_time check_date check_numeric );

or

my %checkers =
   map { $_ => \&$_ }   # \&$_ is except from strict refs.
      qw( check_char check_time check_date check_numeric );

Then in the loop,

my $checker_name = $rec_layout_hash{$fields[0]}{$i}{"sub_routine"};

my $checker = $checkers{$checker_name}
   or die("Unrecognized checker $checker_name\n");

$checker->($value1, $value2);

\&$_ is except from strict refs

Very good point, although I think (?) that's just a specific case of the more general exemption my $x = "foo"; my $y = \&$x; &$y; or my $y = \&{"foo"}; &$y;

[ikegami]

I didn't mean to be exclusionary. \&{EXPR} as a whole is exempt, including the \&$NAME shorthand. CONST->() is also exempt.

For example, (\&$name)->() is the same as $name->(), but it bypasses the symbolic reference check requested by using strict.

Thanks to everyone for your input, a number of options to consider. Much appreciated.
