Here is a copy of what Dennis had written to me regarding automatic impleme=
ntations from C# (the model):

> Originally, C# did not support automatically implemented properties.=20
> There are several reasons why they were added.  The first reason, is that=
 while the syntax for properties is the same as the syntax for member varia=
bles, there is still some subtle differences in behaviour that cannot be ac=
counted for by properties.  Here are some examples:

> - Variables may be used as input to out/ref arguments. Properties may not=
.
> - Properties may throw exceptions - variables will never do that.
> - Properties may have side effects or take a really long time to execute.
> Variables have no side effects and will always be as fast as can be expec=
ted for the given type.
> - Properties support different accessibility - variables do not
> - When using reflection the properties and fields are treated as differen=
t MemberTypes so are located differently (GetFields vs GetProperties for
example)

Some of these above example still apply (reflection, execution time), so th=
e automatic implementations may simply be there as a way for authors to ind=
icate their intention to make them execute code at a later time.

This suggestion below shortens the syntax even further.

How it is different from just public $Hours and why one would need this?
