So is Perl accessing modules without checking the surrounding directory?

Perl is asking the operating system for the files. If the OS thinks it's OK it returns the contents of the files, otherwise it doesn't and one gets permission denied. In my linux, reading a file is permitted when the surrounding directory has "x" set (executable bit) for the reader user.
