Please see my newest scope proposal, which I just posted here:
http://forum.dlang.org/thread/tlupkiiarrabqaxtayci@forum.dlang.org#post-tlupkiiarrabqaxtayci:40forum.dlang.org

It does almost what you suggest, but only for @safe functions, to 
avoid breaking too many things. A change à la "@safe by default" 
would then have the same effect.
