Have you ever wanted a quick and easy way to combine arrays in ColdFusion.  I have done this a number of ways in the best, but came across this gem and thought I would share.

All ColdFusion arrays are of the Java vector type, we can use the underlying java.util.Vector class methods, specifically the addAll() method.

Keep in mind that this is not a "documented" use of arrays in ColdFusion, so at any version it may stop working.

Merging two arrays in ColdFusion with the java.util.vector.addAll()

ar1 = ["a","b","c"]; ar2 = ["d","e","f"]; ar1.addAll(ar2); writeDump(ar1);

Copy of BoxLang AI 3.4 Blog Series Part 5 : Reasoning Without the Guesswork

Reasoning-capable models have been usable in BoxLang AI for a while. params passes straight through to the provider body, so params: { thinking: { type: "enabled", budget_tokens: 10000 } } for Claude, or params: { reasoning_effort: "high" } for OpenAI, already reached the API. What never worked was reading the reasoning back. It was parsed out on arrival and silently dropped. In 3.4.0, that's fixed, and it's fixed the same way for every provider.

BoxLang 1.17 Series Part 4 : WriteDump Enhanced!

You call writeDump() on an ORM entity or a very rich class graph . The browser locks up. Thirty seconds later you get a page with forty thousand rows on it, you scroll for a while, you give up, and you go edit your code to dump a sub-key instead. Or worse, you crash the server.
