Yes, +1 for the defaulting functionality: tremendously useful, makes for more elegant templates and code.

But I like more the syntax suggested by srid for specifying the default: 

+ more similar to what other popular templating languages do, XSLT for one but also some java-based I think
+ makes templates more useful when looked at in a browser by themselves (w/o nevow rendering), when testing the l'n'f

just my .02
