CamelCasing a Constant: Acceptable Practice?

[kyonides]

"...methods are lowercase."

Eh... not always, check Math::PI and Math.PI, they're the same thing, possibly it's because they defined a method like this

Code:

module Anything
  def self.Mymethod
    puts 'Who cares?'
  end
end

This is a working scriptlet... It's related with triangle sides.

Code:

class TriangleError < StandardError
  def to_s; 'Wrong lengths for sides' end
end

def triangle(a, b, c)
  raise TriangleError unless TriangleSideLengthsValid?(a,b,c)
  return puts :equilateral if [a,b,c].uniq.length==1 # all sides are equal
  return puts :isosceles   if [a,b,c].uniq.length==2 # 2 sides are equal
  return puts :scalene     if [a,b,c].uniq.length==3 # no sides are equal
end

def TriangleSideLengthsValid?(a,b,c)
  ax,bx,cx=[a,b,c].sort
  return (ax+bx)>cx
end

In this example...

triangle(20,20,35) #=> isosceles

...would belong to the Object class (or BasicObject class if you prefer in Ruby 1.9.1) for those newbies who didn't know about this.
