Self is not so much a concept as an object. The default object.
There is always only one self, but what that is may change. Like a narrator in a book with multiple first-person identities.
puts "top level"
puts "self is #{self}"
class C
puts "Class Definition Block:"
Local variables hold their value during a particular section of code. Local refers therefore to their 'scope' this can be seen through the value of the variable x below:
ruby-1.9.2-p0 > def support_united
ruby-1.9.2-p0 ?> x = "I Support United"
ruby-1.9.2-p0 ?> puts x
ruby-1.9.2-p0 ?> end
ruby-1.9.2-p0 > def support_city
ruby-1.9.2-p0 ?> x = "I Support City"
#Numbers
Numbers take the form of Fixnum, Bignum (Class: Integer from Class: Numeric) or Float(Class: Numeric) there are others but they are part of the Standard Library, these are Complex, BigDecimal and Rational - these are not covered here. I can't be arsed. Sooo...
