Subject: Operator precedence of exponentiation (**) and complement (~)


The operator precedence table at:

 http://phrogz.net/ProgrammingRuby/language.html#table_18.4

states that the exponentiation operator (**) has higher precedence than
the complement operator (~). Ditto for operator precedence in Python.

Yet the following program:

 x = ~2**3
 print x, "\n"      # prints -27 in Ruby; prints -9 in Python

surprised me by printing -27 (I am using ruby 1.8.6).

BTW, the following program prints -9 in both Ruby and Python:

 x = ~(2**3)
 print x, "\n"

Is this a Ruby bug?

Thanks,
