I would argue that functions that *always* return a single

the empty list in case of an error.
Whereas I would argue that should return *nothing* in case of an
error. It's a philisophical question so we could go back and forth
all day. :)
my %h = ( a => func('a'), b => func('b' );
Now suppose func('a') sometimes returns the empty list,
so all code then becomes like this:
my %h = ( a => ( func('a') // undef ), b => func('b' );
Etc. etc.
