The 'use strict' and 'use warnings' are absolutely NOT 'imported' into the calling scope.

I don't need your help writing a test case. Apparently you need mine. Here it is:

t100.pl: 

#!/usr/bin/perl 

use strictandwarnings;
# use strict;
# use warnings;

# my $x;
print "$x\n";

$x = '$y';

print header(), start_html(), "\n";

strictandwarnings.pm after "fix": 
package strictandwarnings;

require Exporter;
our @ISA = qw(Exporter);

sub import {
   my ($pkg) = (caller)[0];
   my $current = __PACKAGE__;
   eval qq[
       package $pkg;
       use strict;
       use warnings;
       use CGI qw/:standard/;
       package $current;
   ];
   # optionally, if you still need import:
   goto \&Exporter::import;
}

1;

t100.pl as is runs to completion with no warnings.

Un comment 'use strict' in t100.pl and it barfs with: 
Global symbol "$x" requires explicit package name at ./tst100.pl line 
+9.
Global symbol "$x" requires explicit package name at ./tst100.pl line 
+11.
Execution of ./tst100.pl aborted due to compilation errors.

showing that had your code worked, the rpgram shouldn't have.

recomment use strict and uncommmment use warnings in t100.pl and it produces: 

Use of uninitialized value in concatenation (.) or string at ./tst100.
+pl line 9.

followed by the correct output.

Your initial code said it did 3 things. It did none of them. 3 is more than 1. Hence 'multiply broken'.

And the OP did in fact use 'use strict' and 'use warnings' in the oringinal post. SOrry for not being a mind reader.

Note to whoever else keeps --'ing me: Have you tried to test the code, or do you just beleive this other guy when he says it works? Update: the original version of previous was much harsher, suspect that that is what was dissed.
