Me thinking about Markdown Extra: if you're using the colon for that
as previously suggested, you're breaking the definition list syntax:

Hello there!

: Is this some code or a definition?

So I will suggest something else.

It's not uncommon to see unindented code samples in email and
elsewhere denoted by a simple separator line -- I've got an
impressive number of bug reports for PHP Markdown formatted this way.
So we could build on that and introduce an unindented code block
syntax with a separator line. While the aesthetics are not as good as
indented code blocks, that syntax could prove handy when indentation
is not very practical (like, say, pasting a big code sample in a web

So I propose this as an alternative code block syntax:

function db_like($first, $pattern) {
$pattern = preg_quote($pattern);
$pattern = preg_replace('/(?<!\\)_/', '.', $pattern);
$pattern = preg_replace('/(?<!\\)%/', '.*?', $pattern);
return preg_match('{^'.$pattern.'$}', $first);

The code block begins with three or more consecutive tildes `~` alone
on a line, and ends with the same number of tildes `~` alone on a line.
