nimtraits

Libraries exist: https://github.com/haxscramper/nimtraits https://github.com/andreaferretti/patty https://github.com/alaviss/union Again we are not new to this problem and already offer alternatives.

Thanks for your reply. It's interesting to know what the perceived weaknesses and strengths are. Nim does have pattern matching but it's rarely used, whereas it seems to be used a lot in Rust (probably because of the prominence of enums). Nim has static lifetime management, but it's mainly used for eliding and thread safety (for now). Traits are an interesting feature, and make a good example of why I'm so bullish on Nim: someone has already replicated them with a macro: https://github.com/haxscramper/nimtraits The popularity critical mass thing is mainly getting eyes on the language, but I think Nim has a slight advantage in that it's incredibly cooperative with its compile targets and FFI. Like Python, it's great for good glue code and 'scripting' without the performance penalty, and I hope that helps it meld into people's toolboxes ove
