For me, it is the indirect value I reaped by lurking in D's 
forums. There used to be some interesting discussions by language 
theorists that pushed me to learn and appreciate quite a bit of 
"abstract nonsense" and shown how many of what I thought was a 
cool new thing was just a hackish reincarnation of an old and 
well explored concept (including mixin templates).
