I am wrong. As I just looked at the source code I saw that there is
already a method (_md5_hex) that can be used to get the checksum as
string.
#!/usr/bin/perl6
Q:PIR {
load_bytecode 'Digest/MD5.pbc'
.local pmc md5sum, md5_sum_get
md5sum = get_root_global ['parrot'; 'Digest'], '_md5sum'
$P0 = md5sum('foo')
md5_sum_get = get_root_global ['parrot'; 'Digest'], '_md5_hex'
$S0 = md5_sum_get($P0)
say $S0
}
