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.

Ineptocracy
(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
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.
