Re^2: Odd number of elements in anon hash

Thanks! I guess I'm not so familiar with the basics of "referencing" (I'm not even sure if that's the right name).

so, when you use [ ... ] - does it return a reference to the enclosed an array? I think I was taught to use something like \@{...}. Does it mean the curly should be used only for hashes?

`[ ... ]` returns a reference to an anonymous array. `{ ... }` returns a reference to an anonymous hash. In the appropriate syntactic context like assignment, that is. Curlies are used for various things, for example a block, or to group/disambiguate when dereferencing, like `@{ $obj->method_that_returns_an_arrayref() }`.	[reply] [d/l] [select]
