def blank?
  self !~ /\S/
end

#constantize ⇒ Object

Tries to find a constant with the name specified in the argument string:

"Module".constantize     # => Module
"Test::Unit".constantize # => Test::Unit

The name is assumed to be the one of a top-level constant, no matter whether it starts with “::” or not. No lexical context is taken into account:

C = 'outside'
module M
  C = 'inside'
  C               # => 'inside'
  "C".constantize # => 'outside', same as ::C
end

NameError is raised when the name is not in CamelCase or the constant is unknown.
