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).
