Is the if()if()if() cascade really needed? I can see a reason that an
extra 'if' is preferred for the variable declaration of orig_decl, but
can't we at least put the new 'orig_decl != expr' with an '&&' into the
same if as the decl/in the second if? Besides clearer, it also avoids
further identing the return line.

Thanks,

Tobias
