I'd love to hear John and Sean's latest thoughts on this.  I've often 
felt that this was one of the main weak areas of Radius (and why there 
are now several <r:if_misc_stuff> tags to fill the void).

In the meantime, I have an extension that I developed to test this 
functionality (actually both conditionals and variable declarations).  
John has encouraged me to put it out there for more people to 
try/critique but I wanted to split the two functionalities up first (it 
was just a proof of concept for me).

Anyway, it is pretty usable (though it could use some lovin).  You can 
get it here:

Also, there is the Backdoor extension which basically opens up ERB into 
your tags so you can use all of ruby's goodness within your tags.  It 
also addresses the need for <r:if> tagging.
