Stop thinking in terms of bitwise; this is Boolean. The "evaluated expressions" are logical values. 2 is logic-true, 3 is logic-true, 2 and 3 returns 3, which is logic-true. It uses the last evaluated expression as the logical value.

C:\usr\local\share\PassThru\perl>perl -le "print +('george' and 'graci
+e')"
gracie

C:\usr\local\share\PassThru\perl>perl -le "print +('0' and 'gracie')"
0

C:\usr\local\share\PassThru\perl>perl -le "print +('' and 'gracie')"


C:\usr\local\share\PassThru\perl>perl -le "print +('george' and 'false
+')"
false

C:\usr\local\share\PassThru\perl>perl -le "print +('george' and '')"


C:\usr\local\share\PassThru\perl>perl -le "print +(2 and 4)"
4

C:\usr\local\share\PassThru\perl>perl -le "print +(2 && 4)"
4

C:\usr\local\share\PassThru\perl>perl -le "print +(2 & 4)"
0
