Perl 6:

0/FALSE: 0, "0", "", undef ("0" is true if the type is Str)
1/TRUE:  everything else

 AND    OR     XOR   NOT
+&     +|     +^     +^    <-- bitwise, numeric
~&     ~|     ~^     ~^    <-- bitwise, string
?&     ?|     ?^     ?^    <-- bitwise, boolean
&&     ||     ^^     !     <-- logical, high precedence
and    or     xor    not   <-- logical, low precedence

The difference between logical and bitwise boolean is that logical AND and OR return an operand, while bitwise AND and OR return boolean values (the original values are lost).
?^/^^, and ?^/! are practically the same.
^^ was missing in Perl 5.
+^, ~^, ?^ are both XOR and NOT, depending on whether they are used infix (in between) or prefix (in front).
