[5:08pm] allie_p: is an instance variable and an instance method the same thing?
[5:09pm] saturnflyer: no
[5:09pm] saturnflyer: an instance variable is some internal value
[5:09pm] saturnflyer: an instance method is some function that object can perform
[5:10pm] allie_p: ok, so they're related but different
[5:10pm] saturnflyer: typically, you might keep the names the same to set and retrieve the instance variable values
[5:10pm] saturnflyer: attr_accessor creates 2 methods that set and retrieve the instance variable
[5:10pm] saturnflyer: but you could have a method called full_name, that returns something other than @full_name
[5:11pm] saturnflyer: it could be @__full_person_name, or whatever you want
[5:15pm] allie_p: thanks!

# This is the code from my 'There is No Such Thing as Metaprogramming' talk,
# which premiered at the Arlington, VA Ruby Users Group on Feb 22nd.
# Without the deliver and walk-through to the solution below this example
# will be missing quite an important bit of content (mainly the tracking of
# 'self' while developing the solution, but it still a useful read.

# Here is the Toddler with no metajuju. Note that the developer, as well as
# the code, is completely unuaware of the interpreter. A developer with a
# background in compiled languages would be comfortable looking at this.
