How to expand hash into argument list in function call in Perl?

How to expand hash into argument list in function call in Perl? I am searching Perl equivalent of Python's syntax : so开发者_StackOverflow社区mefunc(**somedict) or somefunc(*somelist). Is that possible in Perl?

In Perl, all function arguments are passed as lists and stored in the special array variable @_. You can copy those values to some other array, or directly into a hash (as you can with any array/list).

If you are writing a function, you can pass the arguments directly into an array or hash:

sub hashFunc {
    my %args = @_;

    ....
}

sub arrayFunc {
    my @args = @_;

    ...
}

To call a function like that, just pass them as if they were a list or hash:

hashFunc(arg1 => 'someVal', arg2 => 'someOtherVal');
arrayFunc('someVal', 'someOtherVal');

If you already have the arguments in a variable, just pass them along and Perl flattens out the array/hash into the argument list:

hashFunc(%someHash);
arrayFunc(@someArray);

Hashes do expand into a list when calling a function:

my %h = (a => 1, b => 2, c => 3);

sub foo {
  # prints the key-value pairs in unsorted order
  print "@_\n";
}

foo %h;
