oh, i meant do all those safely. of course you can take refs as it is
just a hash anyway (but with side effects). but passing around a ref to
a symbol table entry is leading to even more disasters at a
distance. passing refs to globs is an old perl technique (as is passing
globs themselves which dates from perl4).

that is my main point. there is no reason to use symrefs for data
structures and many reasons not to.
