By index or by value? Let's see... 'splice' can already be used for a
simple delete-by-index and I suppose 'defined' would pass as an
exists-by-index. I guess, then, that you want these to operate by
value on arrays, which wouldn't really be very consistent with their
behaviour on hashes, where they use the index.

At first glance I thought you were kidding about file test operators
on regular expressions until I realized these would be useful:
    'Total size of *.html'  => -s /\.html$/
    'Hidden subdirectories' => [-d /^\..*/]

So '-d /^\..*/' would be interpreted as:
    opendir _FOO, '.'; grep {/^\..*/ and -d $_} (readdir _FOO); closedir FOO;

Of course having it handle multiple directories (as in
m#/.*/.*\.html#) would be necessary - perhaps the ** globber from the
Perl shell could be used here.

That reminds me, it should work with globs too while we're at it:
    'Total size of *.html'  => -s <*.html>

Is there actually serious discussion about doing things this way?
