Allow highlighting certain bits of a code fragment or quote

Would it be possible to add a "Highlight" function to code blocks?

For example, with

function foo ($fbar = false)
       echo 'Hello'

the echo statement could be highlighted so that responders can see clearly where the error is being caused.

The reason I think this would be a good idea to implement is that the posted code may only be a snippet from their source and the line numbers that the compilers throw would be different than the line numbers within the snippet.

On http://pastebin.com, before it was taken over by new owners, you had the choice to place an @ symbol at the head of a line to highlight the line.

What are your thoughts on this?
