This node is inspired by the following (excerpt from the) comment by BrowserUk in Re: Re: Re: looking for a regex

s_\{.*?\}_{$sub[$n++]}_g;

I'm not at all sure about using _ as the delimiter, but everything else I tried was altogether too messy.

Assuming that the traditional '/' is not available, I would have written that as one of the following

# For the sake of the discussion lets ignore the fact the 
# curlies didnt need to be escaped.
s!{.*?}!{$sub[$n++]}!g;
s:{.*?}:{$sub[$n++]}:g;
[download]

And I certainly wouldn't have done what I know is popular amongst some monks

s#{.*?}#{$sub[$n++]}#g;
[download]

Because I find it makes the code hard to understand at a glance, especially in an editor that doesnt know that the # in this context isnt a comment begin marker.

So what are the monks at large opinion on this ever so trivial a subject? Which alternate regex delimiter do you favour? And what are the arguments behind your opinion (if any)?
