I think I may understand what your problem is now. If you call myFunc
inside your function, it's actually attempting to call the variable
myFunc. Remember that myFunc is a reference to your function. If you
make it point to a different function then your environments will
"collide" as you said. What you can do instead is define a local that
refers to your function like so:
do
local x;
x = function() ... x() ... end
protectedEnv(x);
myFunc = x;
end;
