    Thanks.

    Good trick.

    Anonymous array - then convert the ref. back to array and apply scalar to it.

      Also works for "highest index" rather than "number of elements": 

      >perl -wMstrict -lE
"say scalar $#{[ 'aa' .. 'zz' ]};
"

        Or insert commata and count them ;-) 

        perl -wE "say 1 + join(',','aa' .. 'zz') =~ tr/,//;"
