Setting up an alias in your shell's rc file helps - for bash:

alias sperl='env PERL5OPT="-Mstrict -Mwarnings" perl'

You keep running your oneliners without strictures; but if something blows or feels fishy, you just interrupt and type

prompt$ s!!
[download]

to run your latest command under strict and warnings.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
