You have to provide a list of values on the right hand side. For example, you can try:

@hash1{@array} = ('value') x @array; @hash2{@array} = 0 .. $#array;

    Hm... makes sense. But how do I handle it if I don't know the size/length of the array? Do I really have to check that and then programmatically build an array in a loop? Or is there a syntactical shortcut?
      I do not understand. In my examples, the size of the array is not hardcoded, it is dynamically computed from @array in the scalar context or $@array.
