[Puppet Users] passing arguments by name instead of position for functions

['Matt Zagrabelny' via Puppet Users]

Hello,

I have a variety of hashes that have similar content:

$h = {
    'foo1' => 'bar',
    [...]
    'foo99' => 'baz',
    'foo100' => 'h',
}

$g = {
    'foo1' => 'bar',
    [...]
    'foo99' => 'baz',
    'foo100' => 'g',
}

I'd like to have a function or similar mechanism:

$h = helper_module::get_hash_defaults()

but be able to override various keys/parameters in the get_hash_defaults 
function:

$h = helper_module::get_hash_defaults(
    'foo100' => 'h',
)

$h = helper_module::get_hash_defaults(
    'foo100' => 'g',
)

but functions only take parameters by position.

Does anyone have any clever hacks I could try to mimic passing arguments by 
name?

Thanks for any help!
