First note/caveat: I'm not interested in any solution involving IFS, for
two reasons:
    1) IFS-based solutions never work for me.
    2) Changing IFS is inherently dangerous, because, well, IFS itself
     inherently dangerous.  Yes, I know it has been somewhat de-fanged
recently - but it is still dangerous.

Sorry to bother you, but... could you please give me some hints? Why
dangerous? Thanks. :-)
 

Anyway, the point of this thread is that I have recently developed a
good solution for this, using bash's "mapfile" command. 
[...]
mapfile -td ';' <<< "$foo"

Yes, mapfile is a good solution. Of course, when you use <<<, no word
expansion is performed, so IFS is out of the question.

Caveats:
    1) You can only have one, single character delimiter.

But you could have more using IFS. Something like:

| $ IFS=";:[ENTER]
| "
| $ declare myarray
| $ for i in $(echo "one:two;three 3[ENTER]
| four"); do myarray+=( $i ); done
| $ echo ${myarray[@]}
| one two three 3 four
| $ echo ${myarray[2]}
| three 3

What would be wrong with it?
