quite well played!!!!
What we 'play with' in demo code should never be confused
with what we should DO with Production Grade Code....
the second most important rule - in the long run - is
that one should name variables in a way that will help
you remember WHY you are looking at
$got_back_from_FunkCall
remember folks we paid extra to get that "_" accepted
as 'internal' to the 'variable name' - and not as an
'error' case....
