With an Altanta-era rakudo, this works fine:
$ cat foo.p6
eval 'class A { has $.a}; my $a = A.new();';
eval 'class A { has $.a}; my $a = A.new();';
eval 'class A { has $.a}; my $a = A.new();';
say "alive";
$ ./perl6 foo.p6
alive
Assigning ticket to moritz in case he can wishes to add this as a test.
Thanks for the report!
