@RubberDuck By the strictest defintion of "broken", I'd say no.

Phrancis

@nhgrif long time no see! Been alright?

nhgrif

And it doesn't take knowing Swift. Just read the "problem" description.

RubberDuck

Often you're right, but I'm always hesitant to vtc as broken when I'm not comfortable with the language.

Has the mug been around? I found bugz.

nhgrif

And actually, this question probably isn't very answerable.

Because the real answer to his question is that Swift isn't very good with arrays in loops with default optimizations.

Q: Reflection in VBA, getting the vbext_ProcKind

This is a follow up to Extending the VBAExtensibility Library. It turns out that code had a really nasty bug. Anytime vbeProcedure.StartLine got called, I was running the risk of hitting runtime error 35 because CodeModule.ProcStartLine has to be told what kind of procedure it's looking for. Ever...

I feel bad for new users who take all the time to set up their profile on CR, etc. and then post an off-topic question like this @CaptainObvious

Jamal

Same can be said about spammers. :-)

mjolka

@Phrancis yes and no... i mean, on the ask question page it specifically says "The relevant code sections must be included in your question"

RubberDuck

I feel no pity for spammers.

Phrancis

Good point.

Jamal

Of course. But, spammers expect eyeballs, but ideally they'll only be seen by a few people or just one person.

But at least the new users can be educated, although even those questions may be deleted quickly.

@Jamal i get "blah.cpp:8:29: error: '>>' should be '> >' within a nested template argument list" using g++ 4.5.2

either way, there seem to be plenty of errors in that code

Yes, they must be separated if the compiler doesn't support C++11.

you could also introduce a new variable, $fizzBuzzWord = $fizzWord . $buzzWord

Any smart way to eliminate the 2nd line, generated by PHP? (apparently)

mjolka

@Phrancis you can't break outside a loop or switch

Phrancis

Do you know a better way to do this? If I don't break; I get something like this:

E_WARNING : type 2 -- Division by zero -- at line 22
E_WARNING : type 2 -- Division by zero -- at line 25

Should one return; in all if statements in PHP?

mjolka

it depends, return will end the execution of the current function or script, so if that's the desired behaviour then yeah

Phrancis

Makes sense, sort of (to me)... I'm curious as to what a program returns to. But maybe that's a bit deeper than I'm ready for now

mjolka

actually there's some disagreement on using return in global scope here php.net/manual/en/function.return.php (i don't write php, so idk)

should that be $fizzNumber = 3;

If I was to be very verbose I would have written: for ($index = $index; ...)

What is the better/simpler syntax?

declare it as close to use as possible, so remove the line $index = 1 and just use for ($index = 1; ...)

Phrancis

for ($index = 1;...) reassigns the value of the variable (I think?)

mjolka

yes, but you're not using it anywhere else

Phrancis

Oh.

Is it better to declare a variable mid-script, as opposed to the beginning?
