One thing I would be worried about is

instead of
string s = "int y;";
mixin(s);

someone would do
string s = "int y;";
#s;
...
//some point later
y++;

and then try to debug that if something goes wrong.

So would you do this for both mixin expressions and statements?

I feel like limiting it to mixin expressions might actually make 
some of the risk of cryptic stuff happening a little less.
