local functions

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

I see nothing to indicate it is possible, but can we make a helper 
function 'local'?  Just to keep them out of the name-space.  Putting 
'local' in front of a function definition seems not to be an error, but 
it seems to make no difference.  I read that autoload could be used for 
something like this, but that requires separate files for each helper, 
if I understand. Not worth the trouble of 'unfunction'ing them.  Very 
minor issue.
