Re^3: Syntax for casting map to a hash or an array

[haukex]

\@{ [map { $_ => 'fish' } qw(one two red blue)] }

Well, that works but it's a bit wasteful: first you're creating a arrayref with [], then you're dereferencing it with @{}, and then taking a reference to that again with \. It's easier to just use one set of []'s like 1nickt showed (although you may not have seen that yet since it was part of a large ninja edit).

I got there! In the end. Somewhat circuitously ...

I knew this

%{ {map { $_ => 'fish' } qw(one two red blue)} }

returned a hash ...

And I knew Dumper needed a reference ...

And I suspected that if I could successfully pass Dumper a reference to an array I might finally understand what was going on with

%{ { ... } }

that bit.

Thank you very much.

Thanks,
