Nope, not like that.

Note that because the translation table is built at compile
time, neither the SEARCHLIST nor the REPLACEMENTLIST are
subjected to double quote interpolation. That means that if you
want to use variables, you must use an eval():
eval "tr/$oldlist/$newlist/";
die $@ if $@;
eval "tr/$oldlist/$newlist/, 1" or die $@;
Hope this helps,
