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?
Since $HoH now contains a reference to a hash you have to dereference it properly.
delete $HoH->{ $k } if keys %${ $HoH->{ $k } } < $limit;} return %HoH;
return %$HoH;
But you don't really have to return the hash now as you are using a reference to the original hash which means that the original hash is modified by your subroutine.
