in thread transliteration d flag not working as expected

Not sure if it's slower, 'tr///' doesn't allow variable interpolation.

Using it twice in a DRY way means putting the pattern into a variable which leads to eval :(

        Because the transliteration table is built at compile time, ne
+ither
           the SEARCHLIST nor the REPLACEMENTLIST are subjected to dou
+ble
           quote interpolation.  That means that if you want to use va
+riables,
           you must use an eval():

    What I had in mind was that  s/// would be messier/slower if interpolation was unnecessary, as the OPed problem statement seemed to indicate. I agree that if interpolation becomes necessary,  s/// is almost certainly preferable to an eval approach.
