pass all files in directory as one argument to perl script

linux beginner here

I have a directory with 50 files in it and I want to simultaneously pass them all to a perl script with just a space between names , as in...

./perl_script.pl file1 file2 file3 .. file50

The files all have non-numerical names.

I understand how to pass all files to perl script one at a time in loop but I am struggling with passing all the files at once. Any help would be greatly appreciated.
