There are plenty of packages that you can download that provide very useful stuff. The difference with other languages is that Ada people disregard anything which is not blessed by the standard. Many other in-fashion languages have not standard at all, so users consider that anything on the web is "available for the language". If you look at any of the sites that provide Ada resources links, you'll see that Ada's situation is not that bad... Talking about reuse vs. redesign, I recommend the paper "What price reusability", old but fortunately available from ACM: https://dl.acm.org/doi/10.1145/112629.112643 It compares the cost of rewriting with the cost of searching for something already available, and the number of reuses necessary to break even. It shows that for simple things (like the one we discussed above), rewriting can be more cost-effective than searching the web for existing stuff... -- J-P.
