Re^2: Type of arg 1 to splice must be array (not keys)

Thats a good solution. The only problem is that I don't know the number of keys. So I can have more or less. Which means I have to rewrite your solution to

my @k = (keys %mh)[0 .. (scalar keys(%my) <= 100 ? scalar keys(%mh) : 
+100)] ;
[download]

Which doesn't look that good anymore. So I prefer 'splice'. Is there a way to convert this 'key' list into an array ?

Your slice solution is buggy and uses `scalar` needlessly. `my $keys = keys(%my) < 100 ? keys(%mh) : 100; my @k = ( keys %mh )[0..$keys-1];` [download] or `my $keys = min 100, keys(%mh); my @k = ( keys %mh )[0..$keys-1];` [download] (List::Util provides `min`) A `splice` solution: `my @k = keys %mh; splice( @k, 100 ) if @k > 100;` [download] You need the conditional to avoid the warning.
