Why Change [ ] to be { } in ASP.NET Routing?

I noticed that there is one change about ASP.NET Routing. I cannot understand why such change.

In ASP.NET MVC Preview, the routing setting in Global.ascx is like "[controller]/[action]/[id]". Now, it is changed to be "{controller}/{action}/{id}". Why change [] to {} ? Is there some necessity to do that?

In a route, you define placeholders (referred to as URL parameters) by enclosing them in braces ( { and } ). The / character is interpreted as a delimiter when the URL is parsed.

So now why they changed their code for parsing placeholders from [ ] to { } is something which the developers would know better!!!

Wow, that happened a long while ago. Someday, I hope that the string class itself is augmented with named formats. Then this move will look like a very prescient move. We liked its similarity and consistency with string.format. Also, it is consistent with the UriTemplate format string.

I'm not sure it's the reason why, but it does have the benefit of being much more like String.Format. Convention/less surprise is usually a good thing.
