This lets you add dynamic properties accidentally (by putting too many entries in the array or misspelling a property as a key), this method does not let IDEs help you with the construction of the array, or even what's valid for each value in that array and doesn't provide any language level protection against misspelled properties. Of course, for the last point, I'm assuming that this idea works like the following: class Foo { public $prop1; } new Foo () { porp1 = 'foo' // undefined property error of some sort }; > Best, > --Matt >
