You can try wrapping them in ${} and they'll work again, i.e.:
$ docker run -it --rm perl:5.36 perl -E'$00="foo";say"$00"'
Numeric variables with more than one digit may not start with '0' at -e
line 1.
$ docker run -it --rm perl:5.36 perl -E'${00}="foo";say"${00}"'
foo
The ${00} syntax also works in previous Perls, from what I can tell.
