Not all attributes, but some of them.

Ah, thanks, this explains it ;-). However, it's kind of uncool
that this only works for templates...
I've gotten into the habit of templating every function, even if
its a zero-parameter template, because trying to manage all the
pure/safe/const/nothrow annotations myself always winds up
putting me in a corner once the code starts to grow. It's not so
bad, really, one advantage is that you can define functions that
may or may not compile, but will only trigger an error if they
are called on a type that doesn't support it. You can issue
compile time branches using "static if (is
(typeof(function_name)))" to gain an extra degree of control over
this process.
