Re: Succinct switch statement

Altho the given-when thing is cool, it would be cooler if the given() could be left out.

It can. given just sets $_, and the outer while-loop does that already, so it's really redundant.

And, by the way, is there an even shorter way to do print "\n"; ?

No, it can't. You get error `Can't use when() outside a topicalizer` (5.10.1).	[reply] [d/l]

I tested it with a `for` loop, which works. The difference seems to be that `while` doesn't limit the scope of `$_` in any way.	[reply] [d/l] [select]

And `say` prints `$_`, doesn't it?	[reply] [d/l] [select]

And say prints $_, doesn't it? Do you see any mention of `$_` in The Fine Manual? I don't. If you don't believe the documentation, you could always write your own code to answer your own question.	[reply] [d/l]

No, but I see mention of "just like `print`". And `print;` prints `$_`, so it's a safe assumption that `say` does as well, only with an implicit `\n`.	[reply] [d/l] [select]
