I am wondering if we can load a HOA in a similar way. I have always used the following: 
use strict;
use Data::Dumper;

my %hash;
while(<DATA>)
{
    chomp;
    my $line = $_;
    my $key = (split/\t/, $line)[0];
    
    push @{ $hash{$key} }, $line;
    
}
print Dumper(\%hash);

__DATA__
1    a    101
1    b    110
2    c    201
3    d    301
3    e    310
3    f    320
4    g    401
