Attributes were one of my biggest hurdles when working on my own 
projects. For example, it's a huge PITA when you have to add a 
debug writeln deep down in your call stack, and it ends up 
violating a bunch of function attributes further up. Thankfully, 
wrapping statements in debug {} allows you to ignore pure and 
@safe violations in that code if you compile with the flag -debug.

Also, you can apply attributes to your whole project by adding 
them to main

void main(string[] args) @safe {}

Although this isn't recommended, as almost no program can be 
completely safe. You can do it on a per-file basis by putting the 
attributes at the top like so

@safe:
pure:
