Standard Perl 6 has just these non-English variables:
* $_ means "it"
* @_ means "args"
* $! means "current exception/error"
* $/ means "last match"
* $0 means $/[0], the first captured value of the last match
All other system variables have understandable English names, eg:
* $IN means the STDIN object/handle
$OUT means the STDOUT object/handle
%ENV means a hash (dict) of system environment variables
$PID means the system process id
$*KERNEL means the operating system kernel running under
Etc.
