Not sure what to think about this (https://trycf.com/gist/840a89cfaba4f37690377e4c01f5d599/lucee5?theme=monokai):

try {
    throw "hi";
} catch (any e) {
    writeDump(cfcatch.message); // should be e, but still works
}

On CF it - correctly - errors. Probs doesn't matter too much. Just spotted it in a pull request here and was thinking "that shouldn't work..."

i remember at some point (long ago) reading that cfcatch was some non-threadsafe global. i don't remember which engine(s) or much else about it.
