in reply to (Windows) verbatim command line arguments inside Perl script
Is there any way to access the "raw" command-line in order to catch quoting and escaping?
Wrong question. You are trying to build a shell command, so the question is how to convert strings into shell command arguments. For that, there's Win32::ShellQuote's quote_cmd.
use Win32::ShellQuote qw( quote_cmd ); say quote_cmd("some_cmd", @ARGV);
