I personally believe that perhaps this is a good situation to remind yet another time that 5.10.0 supports a lexical $_: if I only change 

foreach       (@fits) { suck_this($_) ; } ;

[download]
in your code to 
show_fits() ;

{
    my $_;
    foreach       (@fits) { suck_this($_) ; } ;
}

[download]

then I get

C:\temp>perl osha.pl
Fits: 5, 6, 7
 Read: 'Fit I'
 Read: 'Fit II'
 Read: 'Fit III'
Fits: 5, 6, 7
 Read: 'Fit I'
 Read: 'Fit II'
 Read: 'Fit III'
Fits: 5, 6, 7

Here, I localized the lexical behaviour to a scope closest to the loop. But if I like it, I may set it once and for all the script say at the top of it. Of course, I may also do the same thing for one loop only:

while (my $_ = <$fh>) { ... }

but I don't like to assign explicitly to $_, and in that case I would probably use a named lexical variable.
