04:31 <FromGitter> <dorianmariefr> @Blacksmoke16 that's the only way I found to share a variable between specs, e.g. no "let", no "def"

12:47 <FromGitter> <Blacksmoke16> @dorianmariefr You can define a private method outside of the test code and use that. Or just define the variable in each `it` block

14:17 <FromGitter> <Blacksmoke16> also i will say you're doing some crazy stuff 😅, looking into that invalid memory access i was able to cause like 4 diff compiler errors/bugs xD

14:17 <FromGitter> <Blacksmoke16> > Program received and didn't handle signal ILL (4) ⏎ ⏎ never even seen this one before ha

22:25 <FromGitter> <moe:busyloop.net> i've seen it before when trying weird macro stuff, but don't remember how i produced it (proc's were involved, it's fairly easy to get funky compiler error when combining those with macros)

22:28 <FromGitter> <moe:busyloop.net> ah yea, after googling: https://stackoverflow.com/questions/7901867/what-causes-signal-sigill ⏎ ⏎ something with missing/wrong return types it seems

23:53 <irc_user> I'm a statically typed language noob, so I'm kind of confused as to why this is allowed in crystal `test = "hello"; test = 5` but not allowed in Rust for example? Is it simply a matter of style/perceived clarity, or is there a performance reason for it? I'm also confused as to why in most languages you have to "declare" a variable with `var` or `let` or `:=`, but in Crystal you don't.

23:53 <FromGitter> <Blacksmoke16> the gist of it is Crystal isnt fully statically typed

23:53 <irc_user> I wonder if there is a book I can read which will give some background on why some static languages work the way they do. Maybe I should dabble in C a bit.

23:53 <FromGitter> <Blacksmoke16> is*

23:54 <FromGitter> <Blacksmoke16> er no, isn't was correct*

23:54 <FromGitter> <Blacksmoke16> its one of its features, where you dont need to type local vars or method args

23:54 <FromGitter> <Blacksmoke16> while still allowing to do so if you want

23:54 <irc_user> Hmm, so it does runtime checks then, which can slow things down?

23:57 <FromGitter> <Blacksmoke16> type is inferred from the values, so probably marginally?
