5.16: Why do I sometimes get an "Argument list too long" when I use <*>?

    The "<>" operator performs a globbing operation (see above). In Perl
    versions earlier than v5.6.0, the internal glob() operator forks csh(1)
    to do the actual glob expansion, but csh can't handle more than 127
    items and so gives the error message "Argument list too long". People
    who installed tcsh as csh won't have this problem, but their users may
    be surprised by it.

    To get around this, either upgrade to Perl v5.6.0 or later, do the glob
    yourself with readdir() and patterns, or use a module like File::KGlob,
    one that doesn't use the shell to do globbing.

so please include as much information as possible and relevant in any

Working code is greatly appreciated.

This is a very minor nitpick, but I thought I'd at least make the

Of course there is no above, since this is excerpted from the perlfaq.
Perhaps it might be better to have it read (see 5.xx) instead?  No,
wait, it can't, because the perlfaq5 document itself doesn't have those
identifiers.  Perhaps (see "How can I translate tildes (~) in a
filename?"), but that's clunky.
