No treatment of symbol tables and globs is truly complete without a walkthrough (or at least a mention) of that wonderous piece of twisted beauty, Symbol::gensym().

    For those intrigued as I was here is a link to Symbol documentation. And a brief cut'n'past from aforementioned docs ...

    Symbol::gensym creates an anonymous glob and returns a reference to it. Such a glob reference can be used as a file or directory handle.

    A search found it used to open a bunch of file handled in the days before you could do lexical file handles (see first answer in Open file issues)

    Cheers,
