Ruby already has this feature, and in my experience syntax highlighters handle it just fine. Here's what vim's default highlighter shows me:<br>

<span style="font-family: "Courier New",monospace;"><span style="color: rgb(189, 19, 152);"><strong>}</strong></span><strong>

So an editor whose syntax highlighting is based on regular expressions already can't cope with the world as it is. :)<br>
<br>
Does anyone reading this know of a tool that successfully highlights python but not ruby?<br>

Concerning that, this is going to place quite a<br>
burden on syntax highlighters. Doing it properly<br>
will require the ability to parse arbitrary Python<br>
expressions, or at least match nested brackets. An<br>
editor whose syntax hightlighting engine is based<br>
on regular expressions could have trouble with<br>
that.<br>
