[Sc-devel] [approve] asBoolean

[Scott Wilson]

The only thing that makes me wonder about this is the existence of  
Boolean:binaryValue. This makes me think that it would be intuitive  
if 0.asBoolean == false. But another solution would be a separate  
booleanValue method.

Don't know what's best...
