er... yer stuck back in C++1.0

There is an inline keyword that does the same thign in 2.0
But I DO still use the .h forma ctually when im writing accessors, which is
most of what yo uwill be calling.  I thin kin the trivial case of an
acessor its actually clearer then having someoen dig through the .cpp file
just to fidn out that its na inline reutrn of a member variable...

My older brother, who works for IBM's TJWatson Reseach Center and is
WONDERFUl for pithy oen liners has said...
"C++ make good programmers better, and bad programmers obvious."

I tend to agree with that.  It forces alot m,ore design thought early in
your projectand if you get the design wrong ya can't easily hack around it,
you need to revisit your design.
I happen to consider these GOOD properties in a language.

I sugges that, like any tool, those wh odon't udnerstadn what C++ is doing
probably shouldn't sue it, or at least not if they want optimal results.
Ever see a newbie pick up a hammer?  They use it in precisely the WRONG way
beause they are acting o nwhat they knwo from the past and don't yet
understand how the hammer works (they "choke up" on the handle.)

If yer gonan try to use a tool optimally ya better learn how it works first
or ya gonna hurt yerself.
