It was an implementation side-effect. It was not intentionally.

The same issue as that, for example, you can specify a variable violating
the naming rules by using:

$GLOBALS["0a\n"] = "Some value";

because it would be bad for performance to check for validness of the
variable-name, and it isn't easy to do either. Nevertheless you should not
trust on this capability: It could change in the future.
