The use of auto in the runnable demos is pervasive across the language
documentation however this is extremely unhelpful when trying to adapt these
demos into useful programs as I cannot infer the type of the variable myself.
There are situations where one may wish to initialise a variable differently
based on a condition and so I will need to forward declare the variable however
I cannot do this because I do not know the type I should be using to declare
because it has been obscured by the use of auto in the demo.
