Source code for a work means the preferred form of the work for making
modifications to it.  For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.

                  <p>Perl is well-known for its <a href="http://www.catonmat.net/download/perl1line.txt">one-liners</a>: short programs written as part of the <a href="http://perldoc.perl.org/perlrun.html">command line invocation of the interpreter</...
Certainly every programmer or sysadmin has the need, from time to time, to do a quick one-off task programmatically.
Such tasks can be done with a full script, to be sure, but once you get the hang of writing them, one-liners can save the time and hassle of actually doing so.</p>

<p>These tasks may include removing unwanted lines from files, collecting data from logs, or even a quick proof-of-concept of something that would become a script later.
They can read lines in files, even multiple files, can operate on files in-place, can read from STDIN as a pipe.
But while one-liners have been tools of the trade for these activities, certainly no such thing would be practical for web tasks, right?</p>

We have even seen how to use the <a href="http://mojolicious.org/perldoc/Mojolicious/Command/eval">eval</a> command to run a one-liner against your app.
So could we take this further?</p>

<p>Could we do remote data fetching and manipulation as a one-liner?
