Another instance of this sort of need is to represent the 
casting/arithmetic magic used in the linux kernel list.h
macros, like 

 void
 inode_to_filename(struct inode *inode)
 {
  struct dentry *dentry = list_first_entry(inode->i_dentry,
        struct dentry, d_alias);
  printk("%.*s\n", dentry->d_name.len, dentry->d_name.name);
 }

where list_first_entry hides quite a bit of stuff that in
our language would expand to @casts etc.  With some more
const-propagation, some of it could be done with an ordinary
script function, but not everything.
