Upi,
In the Moose developers guide the MyClass example has several variables
with an underscore appended (e.g., Vm_), but these are not declared anywhere
that I can see.  I see similar occurrences in the CaConc.mh and
Compartment.mh files.  Are these variables somehow automatically declared?
In Compartment.mh, some of these (A_, B_) are declared in the "private:"
section, but others (Im_, Ra_) are not, so this is very confusing.

Hi, Greg,
   Yes, this is a bit confusing. I haven't really prioritized it, but it
should be possible to massage the preprocessor to deal with these
cases. The reasoning goes like this: All private variables have an
appended underscore. Public field names (which may be associated with a
private variable) do not. However, in the preprocessor .mh file we
sometimes need to define operations on private variables. At this point
the preprocessor just lets those lines through into the generated
files, so we end up using a mix of Vm and Vm_ variable names. It is
easy to keep track of if you remember when you are writing a function
that talks to the private fields.

Hope this helps,
   Upi

I thought that private variable are normally _prefixed_ with an
underscore ?  Is there a specific reason to deviate from the common
convention ?

Agreed, but also to avoid possible confusion with lower-level libraries. If we
were doing system-level work (up through code development tools, maybe), we
might use a single or even double leading underscore.
