I agree with almost all of these, but this one especially.

A side effect of the lack of attribute polymorphism is that 
instead of making things take function parameters, you make them 
templates with alias parameters, making template bloat even 
worse.  For an idea of the impact this can have: I got a 10% 
improvement in compile time on a medium-sized codebase by using 
eager versions of std.algorithm in debug builds.
