Re^2: [OT]: what difference between eval and do ?

grep { s/\d+/a/ } @dd;

This is another instance of a mystery of which I've only recently become aware: The (mis(mis))use of grep in place of the (mis)use of map in place of a for-loop. See this discussion. Just for the satisfaction of my own curiosity, if you or anyone can offer any insight into the rationale behind this strange map/grep usage, I'd be mighty obliged.

This is another instance of a mystery of which I've only recently become aware: The (mis(mis))use of grep in place of the (mis)use of map in place of a for-loop. Definitely agreed that it's a strange (mis\|ab)?use of `grep`, but the `map` variant seems pretty canonical to me - it transforms the elements of a list and stores the resulting new list. The only thing that strikes me as questionable about it is that it overwrites the original list with the new one.	[reply] [d/l] [select]

This is just a case of "When all you have is a hammer, everything looks like a nail". Drives me nutty too...	[reply]

Update: indeed I was able to reproduce it. My JS add on to produce monastery html tags plays a role here because multiple clicks produce different messages. A nonce could solve this. .. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Wikisyntax for the Monastery}	[reply]

I think these duplicates are caused by multiple clicks on send button because of a delayed response. Not sure if I have to blame my tablet's browser, my wifi router, my dsl provider or the monastery. probably all of them. Trying to reproduce it. ...
