Re: RFC idea: Block scoped variables with "let $x = expr"

Hi Tyson, I think this is an interesting idea, but the way you describe it does seem to introduce a lot of caveats and additional restrictions. For instance, this feels very odd to me:

Correctness would be enforced as a best-effort at compile-time - the variables would continue to only be freed at the end of the function call.

Intuitively, I would expect this: {

    let $x = new Foo;
    $x->bar();

} somethingElse(); to be equivalent to this: let $x = new Foo; $x->bar(); unset($x); somethingElse(); Could you explain a bit more what the difficulties are in implementing it this way? Regards, -- Rowan Tommins (né Collins) [IMSoP]
