5.17: 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.

are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
