Packages and Subpackages - style question

[William Starner]

I'm writing a library that has some high level routines that interface to some
lower level routines. These lower level routines can be used directly, just with
more care, and more worry about changing versions.

Is it more appropriate to name the lower level packages nla23.internal_blah or
nla23.internal.blah? That is, should an empty package nla23.internal be made
soley to hold the internal structures?

I vote for the "empty" package. At some point, you may find something
that belongs there, like exceptions or constants that are common. A
version number would be a good candidate.

This is entirely a matter of taste and you should use whichever appeals 
to you more. However, if there are many low-level packages, using 
Parent.Low_Level.Whatever allows the client to "use Parent.Low_Level;" 
and then refer to the low-level packages simply as Whatever_1, Whatever_2, 
and so on.
