Hello:
1.9.3p194 :014 .blank?
= true
1.9.3p194 :015 [, ].blank?
= false
Proposal: the second line should also produce true.
Thoughts?

Michael,
That array isn't blank, empty strings aren't the same as nils. I think changing
that behavior would be confusing. If you don't want to count those elements,
it's probably best to filter the array for non-blank strings.

If you really want to check for are all the values in this array blank, try:
Geoff,
But from the Rails documentation: An object is blank if it’s false, empty,
or a whitespace string. For example, “”, “ ”, nil, [], and {} are all
blank. That's why I think an array full of false, empty, or whitespace
strings should be empty.

But that's not mathematically accurate.

Yes, we need #blank? to be extra expensive because beginners needn't
control what gets injected in their Arrays. Maybe `{ = }.blank?`
should be true, too?
Here you go:
class Array
def super_blank?
# Go!
end

The array has objects on it, so it isn't blank.
