Both methods seperate the question from the solution, but the latter does so without obsfucation (and in my opinion, with a better presentation).
I disagree with the "better presentation". I prefer the former one. The latter one requires another client-server round, downloading another perlmonks page - with all it's irrelevant stuff like boxes, headers and banner ads. Just for what's often is less than a line of text or code. Very inefficient in user time. It's even worse if you have a post with several replies with masked answers. Instead of getting the original post, and the, say, five masked answers in one HTTP transaction, you need six for the link variant.

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! —
