in reply to Any reason to use the Paws module over aws cli commands in perl script?

Once you need to read values from config files or user input, you'll also need to properly quote them for the command line, as they can contain characters as [{};<> ] etc. That's what a module saves you from.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
