Re^2: Effecicncy of key-only hash

I know it isn't my thread but I had to ask: Can you please explain what you are doing here:

undef(@hash{qw(shave the modern way)});

Why you accessing a hash as an array ? ('@' char)? I am missing something I think ...

The `@` tells you that what you expect to return is an array, and the curly braces `{...}` tell you that what you access is a hash. `qw(shave the modern way)` is a list, so `@hash{qw(shave the modern way)}` is a list ("slice") of items in `%hash` with the listed keys.	[reply] [d/l] [select]

It's a hash slice. See perldata for more information on hash and array slices	[reply]
