Slicing_syntax not equal with method as_slice().

[amosbird]

let a = &[1i, 2, 3][] will compile while let a = &[1i, 2, 3].as_slice() will not.

Running that code in the playpen, both lines fail to compile with "borrowed value does not live long enough". Perhaps you narrowed down your example code too far?

[amosbird]

@shepmaster You should comment out one of these lines to see the result I get. http://is.gd/1kl7Iu will compile while http://is.gd/gxGopO will not.

@amosbird Actually, now I see only the one error for my original link. Perhaps the playpen was updated between our two comments? Maybe this is a recent change (or maybe I'm just crazy...).

The result I get right now is that let a = &[1, 2, 3][]; compiles and let a = &[1, 2, 3].as_slice(); doesn't.

Marking this a low-priority as the as_slice method is currently deprecated anyway.

Both of these syntaxes aren't needed (we removed slicing syntax and .as_slice() is deprecated) so I'm closing as it's not really relevant. Thanks!
