def classify(dashed_word)

classify('job-name') # => 'JobName'

Given a word with dashes, returns a camel cased version of it. 
def classify(dashed_word)
  dashed_word.split('-').each { |part| part[0] = part[0].chr.upcase }.join
end  # Tries to find a constant with the name specified in the argument string:

def constantize(camel_cased_word)

NameError is raised when the constant is unknown.

end

C = 'inside'

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