Make Red throw it’s own exceptions

[FCO]

The drivers should map db exceptions to Red exceptions

[FCO]

Changes every driver error to Red error. If the error is unknown (every one but the unique constraint error) throws this error (70eff5a#diff-b0a98c0d1d672c1c869329f86d65e76bR29) asking to open an issue about not existing that error.

[FCO]

The error seems to be a rakudo bug.
This works:

MacBook-Pro-de-Fernando:Red2 fernando$ perl6 -Ilib t/10-alternate-relation-modules.t 
ok 1 - create table for Person
ok 2 - create table for Post
ok 3 - Create a Person
ok 4 - The object is-a 'Person'
ok 5 - and it is the person we expected
ok 6 - primary key is defined
ok 7 - and it is the value we expected
ok 8 - create a related post
ok 9 - The object is-a 'Post'
ok 10 - and the author-id of the post is the one we expected
ok 11 - post title is correct
ok 12 - post body is correct
1..12

but this doesn't:

That's odd. I'm guessing that it's something to do with the use lib 't/lib' in the t/10-alternate-relation-modules.t

Does:

diff --git a/t/10-alternate-relation-modules.t b/t/10-alternate-relation-modules.t
index c519ce3..e1e505e 100755
--- a/t/10-alternate-relation-modules.t
+++ b/t/10-alternate-relation-modules.t
@@ -8,7 +8,7 @@ use Test;
 
 use Red;
 
-use lib <t/lib>;
+use lib $*PROGRAM.parent.child('lib').Str;
 
 
 use Person;

help?

Its working with the new rakudo version...

Now Red only throws its now exceptions, but it has only 3.
Ill create a new issue to create more exceptions as i find them, but ill close this one!
