[RCR] Object#blank?

[why the lucky stiff]

After some pretty even pro v. con discussion on RedHanded [1], I've
moved the vote to the official RCR site [2].

I present the other popular alternatives in the RCR. So, should this
one fail, hopefully we will still be left with a victor. But I trust my
groomed steed will prevail!!

I can't believe people don't like "vapid?"... it's such a great name!

Cheers,

How about Float#nan?? Makes more sense than having 0 as blank, but
perhaps isn't as useful,

How about Float#nan?

When will Float#nan? return true?

When will Float#nan? return true?

~> irb
001> (0.0 / 0.0).nan?

==== #<TrueClass:0x00000002> true
002> (0.0 / 0.0).class

==== #<Class:0x040a85e2> Float

001> (0.0 / 0.0).nan?

Sure. Thank you.

Interesting, however, that 1/0, which is described as Infinity, returns
false on 'nan?'. Must be some mathematical logic I'm not concerned with.

IEEE FP math isn't the same as regular math. NaN is a specific value, but
there are other non-number values:

009> 1.0 / 0.0

==== #<Float:0x04094c2c> Infinity
010> -1.0 / 0.0

==== #<Float:0x041145f6> -Infinity

Calling zero "blank" is really repulsive to mathematical mind.
Object#vapid? was cute, but why not Object#nought? This covers
the semantic territory both of being void and of being zero.

Perhaps we could just use the literal Latin - .nihil?
