in thread What is the difference between $array[1] and @array[1]?

I don't see any use for @a[4]. I'd want to "fetch element at index 4", but @a[4] reads as "fetch elements at indexes 4". I don't have any problems with it warning.

(Syntax and/or semantics are different in Perl6. This only applies to Perl5.)

I do. It makes the one element list an exception (with an exception to the exception if said list has a trailing comma). `@a[1,2,3,4]; # Ok. @a[1,2,3]; # Ok. @a[1,2]; # Ok. @a[1]; # Warning. @a[1,]; # Good boy, you know the secret handshake.` [download] You don't have a problem with that? I think it's a pointless irregularity.	[reply] [d/l]

No. Never used it. Never had a use for it. Never seen it used, not even in an example.	[reply]
