Thanks,
No need for $count or the second for loop:
John, your one-liner certainly makes my sub looks better.
Either put the scalar first in the list or pass a reference to the original hash.
Now, I also tried with pass by reference
my ($HoH,$limit) = @_;
foreach my $k ( keys %$HoH ) { # This two don't work
delete $HoH{ $k } if keys %${ $HoH{ $k } } < $limit;# What's wrong with my deref?
}
return %HoH;
What's wrong with my deref?
