Hi,
First of, considering that you would only save three characters by
having the ' $e' removed, I don't see how it would make things easier
to learn. I mean if you can't learn that maybe you should look into
something else that's not related to programming :)
Having this: "* Avoid indication of a specific exception type" could
be considered as a possible bad practice, just as you were saying that
catch(\Exception $e) is. Also, it you can add the other ten characters
that you save when typing \Exception but does it worth it?
How do you plan to handle this: * Note that there may only be one
anonymous catch-statement, and it has to be the last one. Throw a
fatal error? If not then what, nothing?
What are the performance downsides of having this check in place? I do
understand that you mentioned: "* Runtime needs to perform less
checks. No need to update the symboltable, no need to check exception
inheritance. " but wouldn't that be replaced by what I'm asking about?
If I could read/understand C better I wouldn't ask for this.
Could you also please elaborate this: "* Better possibilities for
static analysis tools"?
As for: * People from other languages such as C#, Python and Ruby
expect this to work I think it is often pointed out when requesting
features such as function/method return type hinting (I'm planning a
RFC for that), named parameters, threads and other stuff that this
ain't C#, Java, Python, Ruby or whatnot so.. what's the official
position on this? Do we want PHP like the other languages or not (and
I won't say more on this here/now)?
Also, the code sample is not that good. If you want to reflect a good
quality scenario, it should be more like:
while (true) {
try
{
$this->connectToServer();
break;
}
catch (ConnectionFailedException)
{
sleep(3);
}
}
And I think the RFC should also add a: Disadvantages section so that
it could help people looking on it and proving that you've done all
the research correctly.
Thanks
