An automated code fixer in this case would be easy. Before 
looking up on the wiki why we couldn't do @pure @nogc func() I 
considered I could just add a pre-build step which does a string 
replacement on the source code from "@keyword" to "keyword" for 
each keyword which can be used as a function attribute.

Given a change to allowing "@keyword", existing source code would 
just need to be checked for containing "@keyword" and prompting 
to replace it with something else.
