Phobos/druntime still has some ways to go before using it from @safe
code will be painless. Some pretty fundamental functionality still
isn't @safe (mainly some stuff in object.di that basically interacts
with too many other things that marking one thing as @safe will
percolate throughout pretty much everything, breaking a whole bunch of
stuff at once).
I once tried writing a @safe program, and it didn't take very long
before I threw that idea out the window. Once main() is @safe, you're
so straitjacketed that you basically can't write anything too much more
complex than Hello World. (Well, you *could* just slap @trusted on
whatever it is that's holding you back, but then that breaks the promise
of @safe, which defeats the purpose of the entire exercise.)
There's also still a good number of @safe-related bugs on Bugzilla,
several of which involve built-in language constructs that break
@safe-ty outright. Things have improved a bit since I last checked, but
it seems to me that @safe is still not quite ready to live up to its
promise just yet. Maybe in a few more years' time...

I think Walter has mentioned before that attribute inference is the way
to go, and I agree. Once you start writing carefully-attributed code,
you'll quickly find that your declarations become painfully verbose,
which is never a good sign (it encourages people not to use attributes).
However, attribute inference on templates and auto functions (proposed
last year, don't know if it's implemented yet) alleviates a lot of the
verbosity. Hopefully the scope of attribute inference will increase
until it makes attribute use more widespread in your everyday D code.
