Singleton is still an antipattern (in most cases).
If you're affraid that someone will break a convention which says that
the global associative array $foos has string indexes and values must be
positive integers, or that it needs to be an array at all
($GLOBALS['foos'] = new sabotage("haha")), you would be better off in
e. g. C++ with
std::map<std::string, uint32_t> foos;
voila, you don't need to worry anymore! Alas, global variables,
including those hidden behind accessors, are a grievous problem in C++
as well.
It's not control over data types, it's visibility of access that causes
most of the lossage. Wrapping the global in a function doesn't remove
the structural defect.
Been there, done that, got the scars.
