Here, dug out the old reasons: Zeev said: We rarely have parser problems now, we can pretty much parse anything we want. Parsing is a non issue really, it's code generation and data structures that make implementing this very complex in a compile&execute model. I truly think this is not a big deal. I also think that it pretty much never makes sense to use dynamic expressions in static initializers or in default argument values. In the few cases it does, it's easy enough to use the standard tools PHP gives you to implement your code properly. It's not the C++ model, it's a typical compile&execute model. Static initializers and function arguments are more complicated. We might do that, but not in the near future. So basically, we don't "need" it but we might get it later. I disagree, but I'm not the one who would implementing it, I'm only already using it. This does look like a syntax restriction for no good reason. Zeev's arguments are good for not introducing it, but not good for removing it once it was there. Sam
