| pelevesque | Anyone know if I can put unit class Orfeo::API; instead of unit module Orfeo::API if my module is only one class? | 04:52 | |
| Wondering if that would also get precompiled? | |||

| roguerakudev | I don't think it has any bearing on precompilation, but you can definitely do unit class in place off unit module ...; class ... is export { ... } | 05:54 | |
| unit class behaves as if anything after it is within a class block | 05:55 | ||

| librasteve | Looking at some Cro examples on GH i have decided to just use class {} (ie no unit declaration or version in each class file) and then rely on META6.json for version / author for the whole package (maybe i will get corrected here if that’s bad practice) | 13:37 | |

| jgaz | I tried some binary manipulation in Raku recently. There are some nice features, like `msb` but it seems odd to me that the right and left shift operators haven't been implemented. Is there some historical reason for this? I'm mainly just curious. | 19:30 | |
| lizmat | m: say 1 +< 4 | 19:48 | |
| camelia | 16 | ||
| lizmat | you mean like that ? | ||
| m: say 64 +> 4 | |||
| camelia | 4 | ||
| lizmat | jgaz ^^ | 19:49 | |
| jgaz | lizmat. Weird. It's marked as unimplimented in the docs. I must have fat-fingered it, your example works on my end. | 19:51 | |
| lizmat | could you give the URL where it is marked as unimplemented ? | ||
| jgaz | yeah, standby | ||
| docs.raku.org/language/operators | 19:52 | ||
| "Please note that this has not yet been implemented." | |||
| Okay, I think I conflated `~<` and `~>` with `<+` and `+>` which are implemented. | 19:56 | ||
| err... `+<` | 19:57 | ||
| lizmat | docs.raku.org/language/operators#infix_+%3C | ||
| indeed | |||
| jgaz: *phew* | 19:58 | ||

| jgaz | Sorry about that. Well, now that I've made my sleep deprivation evident I have another question... wouldn't a unary version of left and right shift operators be generally useful? This would imply a single shift in either direction, akin to incrementing with `$x++`. | 20:00 | |

| lizmat | fwiw, I don't this improves on readability | 20:06 | |
| jgaz | Fair enough. | 20:07 | |
| Thanks for the help. | 20:09 | ||
| lizmat | yw | 20:12 | |
| jgaz | So, semi-dumb question: when playing around with defining new operators only the Unicode angled quotes «...» seem to work. The ASCII stand-in is <<...>>, right? | 20:45 | |
