the call to foo is after the variable is initialised.

I tested it by echoing gettype($x); both after initialising and inside 
the function

It was fine outside the function  and then returned NULL inside it.

I suspect the problem is in the way I am, 'eval' ing the code.

Provably the eval interpreter doesnt quite handle scope in the same way 
that PHP itself does. And adding a global $x 'passes it up' to the 
calling program.

members of society least likely to sustain themselves or succeed, are 
rewarded with goods and services paid for by the confiscated wealth of a 
diminishing number of producers.
