Please let me suggest once again a reading of How to ask better questions using Test::More and sample data. What I and some other monks would like to see is something like:

my @Tests = (

    [ 'The largest (4 quart{16 cups}) will hold most of a bag of flour
+.',  # input string
      'The largest will hold most of a bag of flour.',                
+     # expected output
      ],

    [ 'I {mistakenly} did not recieve my order (it was a different ord
+er), and they rushed me another.',
      'I did not recieve my order, and they rushed me another.',
      ],

    [ 'Company is good because of: (1) quick service, (2) product rang
+e.',
      'Company is good because of: (1) quick service, (2) product rang
+e.',
      'parenthesized ordinals untouched',  # optional comment
      ],

    [ '...', '...', ],  # another test case
    ...                 # more test cases

    );

This can integrate easily into a Test::More testing framework. Individual test cases should be as short as possible and should always be paired with exact expected output. Degenerate and trivial cases, e.g.,
    ''  ' '  '()'  ' ()'  '() '  'x'  'foo'  etc, etc...
should also be given. (Update: If exceptions may be thrown, a test case or cases should ultimately be written for each exception; see Test::Exception.) Note that this is work you will have to do anyway because you must always build a testing framework for any serious project you undertake!

What I, for one, do not like to see is an invitation to do a lot of work to generate test case input for which I must also guess the correct output; that's your job.
