[Canberra-pm] do read-local.config

[Michael James]

In the perl cookbook it suggests a good way to keep
 local configuration details out of a larger and messier script
 is to put normal perl code into a separate file and  "do"  it.

But in a throwaway line (middle of page 328) it says,
 of course neither the doer nor the done will have access
 to the other's lexical (my) variables.
 
Hang ON! Lets get this clear,  the  done.config  file
 can't create a variable visible to the calling program,
 nor see a pre-existing variable to change it.

What's the point?

Can any of you lexicographers explain
 a way around this, to a bear of limited scope?

PS: the IN-elegance of:	eval `cat done`
 has already been noted.
