From: Shark8 Injection-Date: Thu, 20 Jul 2017 00:02:36 +0000 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Xref: news.eternal-september.org comp.lang.ada:47456 Date: 2017-07-19T17:02:35-07:00 List-Id: While reading up on VHDL I found out about its user-defined attributes and = got to wondering why Ada doesn't have them.
