Re^4: Array/List Strangeness (why)

Sorry, multi-value slices require more complex syntax: @{[1,2,3]}[8,1,9]. The -> only works when you just want one value back. The @{ } form isn't actually much more verbose, but it is rather uglier. There was a patch to allow [...]->@[...] syntax (and I believe there is even a fork of Perl5 that includes such a patch) but it never got applied to official Perl 5 (I don't think I ever saw a good reason given for why it shouldn't be applied, though).

multi-value slices require more complex syntax which is really a pity since it breaks the "always dereference with arrow" rule in PBP. I don't think I ever saw a good reason given for why it shouldn't be applied, though "Mythical" backwards compability? ;-) Personally i'd like to have a pragma like `strict` that bans the "scalar comma operator" ... I have much more trouble than fun with it ... 8( Cheers Rolf	[reply] [d/l]
