Right, this will work with the newest perls (>= 5.6), at least if you use glob() instead of <>.   The problem is:

$ ls Hold/* |wc
/bin/ksh: /usr/bin/ls: arg list too long
       0       0       0
$ ls Hold |wc
  169170  169170 2739945
$ perl -lwe'@x=<"Hold/*">;print 0+@x'
0
$ perl -lwe'@x=glob"Hold/*";print 0+@x'
169170
$

Since 5.6 glob does not use a shell to expand filesystem wildcards.

update:   Gah! tye, of course, is right <Hold/*> is the same as glob"Hold/*".   (No '"'s inside <>.)

The following are all the same:

    glob"Hold/*"
    glob("Hold/*")
    <Hold/*>

but <"Hold/*"> is the same as glob('"Hold/*"'), which doesn't do what you want. I expected it to print 1 instead of 0 but it probably notes that there is no file named exactly Hold/* and so returns nothing.
