Personally, I "loved" using templates in C++, so I must say, when 
I read TDPL, I was batshit excited about templates. enums, static 
if, ctfe... Wow.

Unicode: I thought "cute, this language supports unicode". Just 
reading TDPL's intro about unicode finally made it "click" about 
what unicode *is*. In about a month later, I felt like the 
unicode fucking *master*.

mixin and token strings. I wasn't a huge fan of mixin, but their 
power over macros has grown on me. As for token string, I was 
look "OK... a special syntax for strings representing tokens... 
why?" But I've come to understand how cool that actually is, and 
I use it a lot more now.

classes I didn't use then, and I still don't use now, but I'm 
more of a "low level library writer" kind of user, then building 
useful programs kind of guy :D
