You can put arguments in a file and then open and parse the file inside
perl.

It's not an environment variable. (Check limits.h.)
And remember, that's not the *number* of files/arguments/whatever.
ARG_MAX is the total *memory* that can be used for a new process's

% export FOO=$( perl -le 'print "x" x 2**17' )
% ls
bash: /bin/ls: Argument list too long
