12:14 <FromGitter> <oceanfish81_twitter> Hurry up to to register for https://llvm.org/devmtg/2020-09/ - so we could interact with speakers, during Q&A sessions, to cover topics about C language runtime. That would be helpful to discuss language interop (Crystal/Golang (via gollvm)/Rust/Kotlin Native/Swift) and concurrency/parallelism strategies

13:28 <FromGitter> <Blacksmoke16> i think we get the picture

14:13 <FromGitter> <Dan-Do> > Ha, ok then! ⏎ ⏎ Hi, would you mind sharing your final/working code?

19:33 <FromGitter> <Daniel-Worrall> Got myself a weird edge case of an if block not removing the nil case. Will try to reduce that and file

19:36 <FromGitter> <Blacksmoke16> Not using a getter method by mistake are you?

19:40 <FromGitter> <Daniel-Worrall> Works in a block, doesn't work when I repace it with `if false` (just trying to not run the code without spamming 100 comment lines)

19:41 <FromGitter> <asterite> is the block forming a closure over a variable? if so, there's your answer (type flow isn't done in that case)

19:48 <FromGitter> <Daniel-Worrall> ah, that'll be why

19:49 <FromGitter> <Daniel-Worrall> so it's not the case of `if else` not doing type checking correctly, but the closure not doing type checking at all

19:49 <FromGitter> <Daniel-Worrall> `if false` *

19:50 <FromGitter> <asterite> I think so. If you could show some code I can confirm

19:50 <FromGitter> <asterite> The solution is to assign the closured variable to another variable, inside the block, then check with `if`

20:02 <FromGitter> <Daniel-Worrall> I'll get back to you all on it when I can

20:56 <FromGitter> <herrcykel> @Dan-Do here you go: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5f739f8caaff36059b656c72]
