Perhaps the following will be helpful as a pattern for generation combinations:

use warnings;
use strict;

my $i = 1;
print $i++ . ". $_\n"
  for glob
"{'I','You','We'}{' play',' do not play'}{' soccer'}{' at home.',' at 
+school.'}";

Output:

1. I play soccer at home.
2. I play soccer at school.
3. I do not play soccer at home.
4. I do not play soccer at school.
5. You play soccer at home.
6. You play soccer at school.
7. You do not play soccer at home.
8. You do not play soccer at school.
9. We play soccer at home.
10. We play soccer at school.
11. We do not play soccer at home.
12. We do not play soccer at school.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
