        The 'select' directive's syntax does not correspond to the rest of the 
shell's syntax.
        I am not sure if this is by design; if it is, let me know and I'll go 

It's more like `select' doesn't inherit some of the shell's special cases.

        if ((n > 1)); then {
            select dir in ${d[@]}; do {
            } done;
        else { ...

...but select breaks on the "} done;" syntax

Yes, you need a list terminator so that `done' is recognized as a reserved
word here. `;' is sufficient. Select doesn't allow the `done' unless it's
in a command position. Some of the other compound commands have special
cases, mostly inherited from the Bourne shell, to allow it.
