The problem with opening with "> X is hard to do in Elixir, any ideas?" is that it shuts down any conversation about X. You've decided it's hard, but what if you're wrong? What if you could avoid X entirely by doing Y? What if the context around X makes it also hard to do in Next? Adding a little bit of context really helps open conversations.
The ol' Barrens Chat Law from WoW. Need to find Mankrik's Wife for that level 20 quest? Don't ask "Where is Mankrik's Wife?" instead say "If anyone is looking for Mankrik's Wife I found her by the auction house in Ratchet" and watch 25 players immediately respond that you're wrong and the real location is X.
On a more serious note, while this works it can backfire if someone follows the wrong info too far, and it can make you look clueless if done too much. If you need to do this, I feel the best way is to also phrase it as a question but leading towards the incorrect answer. Something like "I've been trying to get X working in Elixir but keep getting errors. It looks like [library] doesn't support [feature]?"
