in thread perldoc -lf anomaly

I'm not sure about the "another anomaly". You get the documentation of splice for $_, as $_ without quotes is the shell variable which contains the last argument of the last command.

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

    Similar to ALT-. which is introducing the last argument verbatim.

    But what I was really longing for is a variable or hotkey producing the last output , alas this doesn't exist.

    The closest I could find now is `!!` , I.e. to backtick the last command.

    But I'd really love to facilitate this be defining a shortcut introducing `!!` ...

    So I figured out bind '"\e,":"`!!`"' (ESC for ALT) which also works well on termux.

    Put it into your bashrc and it'll help you to incrementally build one liners.

    Dumb example:

    $ bind '"\e,":"`!!`"'
$ ls *re.pl
tst_re.pl
$ echo `!!`        # typed "echo ALT-,"
echo `ls *re.pl`   # expanded history entry
tst_re.pl
$

    Update

    This will nest better when used repeatedly 

    $ bind '"\e,":"$(!!)"'
