in reply to Combining a hash into another

What's wrong with your solution? Another: 

%styles = ( %styles, %SVGcal::styles );

And another: 

@styles{ keys %SVGcal::styles } = values %SVGcal::styles;

You could also use each if memory is an issue: 

while ( my ($k,$v) = each %SVGcal::styles ) {
   $styles{$k} = $v;
}

Update: Added two other methods.

    Re: What's wrong with your solution?

    Mentioning the hash twice, and coding an explicit loop.

    The first one you mention seems to be inherently inefficient, unraveling both into lists and rebuilding. I was wondering if there was already a neat idiom that updated in place.

    I never remember how to "slice" since I do it so seldom; doing it the boooring way was just expedient to getting the code working. So thanks for posting your examples. --John
