in thread How does one get all possible matches from regex?

Is this still a sound advice to give these days? The doc that you link to says:
As of the 5.005 release, the $& variable is no longer "expensive" the way the other two are.
Why Is $& Bad? gives a better technical explanation why one might want to avoid $&. Even so, the issue with $& is perhaps more of a concern for core module writers. Can you point to some recent benchmarks?

On a related note, does study() actually do anything in more recent perls?

[nysus]: What happened to the submit button? All I have is a preview button.
[erix]: perlmonks has become read-only ?
[marto]: erix unlikely, we've had posts within the last few minutes ;)
[ambrus]: nysus: make sure you enter at least two lines for the title and then preview, and read warnings the preview form prints
[davies]: There is an option (I have it set) to force preview before submission. Perhaps your option has been set (accidentally?) and you are not expecting it.
[ambrus]: sorry, I mean at least two words for the title and then preview
[ambrus]: davies: that option is the default. and it's not really "force", it just hides the button.
[marto]: yes, not reading the errors displayed has been a cause of this type of report in the past
[nysus]: Ambrus, ah. I think that was the problem. I'll try. Thanks!
