No, array_map will trigger the autoloader (actually strlen() will trigger
it once first) and the autoloader should then load the array_map function
from the My namespace.
However, if the autoloader does not correctly load the My\array_map()
function then it will be bound to the global function.

I can add some test cases for that if needed.
