This perhaps should be caught on the first line...
$ perl -we '[1]=~tr/3//;'
$ perl -we '[1]=~tr/3//d;'
Can't modify anonymous list ([]) in transliteration (tr///) at -e line 1, near
"tr/3//d;"
Execution of -e aborted due to compilation errors.

The first form is counting the number of '3's in '[1]'. The left hand
side is not modified, so the construction is legal. '[1]' ends up
getting stringified to something like ARRAY(0x1aadf30).
In the second form '[1]' would actually be modified and therefore triggers
the error.
>From the tr/// documentation:
If the "/d" modifier is used, the REPLACEMENTLIST is always interpreted
exactly as specified. Otherwise, if the REPLACEMENTLIST is shorter
than the SEARCHLIST, the final character is replicated till it is
long enough. If the REPLACEMENTLIST is empty, the SEARCHLIST is
replicated. This latter is useful for counting characters in a class
or for squashing character sequences in a class.
I'm closing this.
