Subject: false or true == true .... WTF?

I have the following code:
[code]
templated = nreturns > 0 or nparams > 0
puts "nreturns = #{nreturns}, nparams = #{nparams}, templated = 
#{templated}"
has_returns = nreturns > 0
has_params = nparams > 0
templated2 = (nreturns or nparams)
puts "has_returns.class = #{has_returns.class}, has_params.class = 
#{has_params.class}, templated2.class = #{templated2.class}"
puts "has_returns = #{has_returns}, has_params = #{has_params}, 
templated2 = #{templated2}"
puts ""
[/code]

when nreturns is 0 and nparams is 1 or more I get this output:
[output]
nreturns = 1, nparams = 0, templated = true
has_returns.class = TrueClass, has_params.class = FalseClass, 
templated2.class = Fixnum
has_returns = true, has_params = false, templated2 = 1
[/output]

Both 'templated2' and 'templated' should be true, not 0.  I can't seem 
to duplicate this in irb.  Even in the debugger,
"p nreturns > 0 or nparams > 0" gives true, while "p templated" gives false.

This must be a bug in the interpreter is my guess?  My ruby version is 
1.8.4 win32.

Thanks,
