Re: Initialize an hash with string

[Eliya]

my %inp = (
    KEY1 => 'VALUE1',
    KEY2 => {
        'VALUE 21',
        'VALUE 22',
        'VALUE 23'
    }
)

Note that hashes hold key-value pairs, i.e. the above structure would be more like

my %inp = (
    KEY1 => 'VALUE1',
    KEY2 => {
        'VALUE 21' => 'VALUE 22',
        'VALUE 23' => undef
    }
)

Not sure if that's what you want.  Maybe you rather want an array(ref) (i.e. KEY2 =>  [ ... ]) here?

Yes, sorry I mistyped the value of KEY2 that is an array ref as you pointed out.
