Excellent!

But why does seek(DATA,0,0); go to the start of the file, not the start of __DATA__ ?

andy.

update: so it's a handle for the script itself... on disk, presumably, rather than in memory? shame.

#!/usr/bin/perl -w
use strict;

print "foo\n";

seek(DATA,0,0);

while (<DATA>) {
        s/foo/bar/ and ! /eval/ and eval ;
}

__DATA__

versus 
#!/usr/bin/perl -w
use strict;

print "foo\n";

seek(DATA,0,0);

my @me = <DATA> ;

foreach (@me) {
        s/foo/bar/ and ! /eval/ and eval ;
}

foreach (@me) {
        s/bar/baz/ and ! /eval/ and eval ;
}

__DATA__
