I was unware PHP was a purist, non-OOP language. What is "OO syntax" anyway?
Why can the core not use high-level language constructs too?
Yield is core syntax, but it produces a function returning a generator, which
is an object, and since Iterators use Exceptions, it would be stupid for
Generators, which*are* a class of Iterator, not to.
Actually - shouldn't the discussion on use of Exceptions be sorted out prior to
adding them piecemeal into new functions. If I had a vote I'd certainly ask that
any implementation of generators respected the 'core' code practices. Iterators
are simply an add-on in my design manual and can be avoided - as can yield - but
yield is being brought in at a level where it is more invasive?
Error handling is another growing minefield and needs to be tidied up before
this sort of creep makes it impossible to remove if that is the preferred
option? There needs to be a formal agreement on Exceptions before they are
pushed out further.
