1. Make the syntax checker aware of the new keyword.
Currently I appear to have more than 11500 errors, but the code
works...
2. Make auto completion work again. If I declare some variable to be of
type Some::Thing::Here it's members should be offered by auto-
completion.
3. Hint on using :: to explicitly specify the global namespace for
internal classes (either checking a list of PHP's internal classes or
checking against all classes defined in the current namespace.
4. If more than one namespace is used in a file, make it visible in the
outline. Maybe even if it's just one namespace.
