From Pickaxe, the following are not implemented as methods and thus
cannot be overridden:
&& Logical `and'
|| Logical `or'
.. ... Range (inclusive and
exclusive)
? : Ternary if-then-else
= %= { /= -= += |= &= >>= <<= *= &&= ||= **= Assignment
defined? Check if symbol defined
not Logical negation
or and Logical composition
if unless while until Expression modifiers
begin/end Block expression
