No. At least not per se. If you feel more comfortable doing it in Go in preference to Rust that choose Go. Another person might have a different background and therefore choose Rust. The programming languages do not provide the disambiguation, it is about the programmer(s), the audience, and the context. -- Russel. === Dr Russel Winder t: +44 20 7585 2200 41 Buckmaster Roadm: +44 7770 465 077 London SW11 1EN, UK w: www.russel.org.uk -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.

I am giving the module system in Go 1.11.2 a whirl to get projects out of the GOPATH environment. The dependencies include ones that have no tagged versions in the Git repositories.

Some of us have been going round various programming language mailing lists complaining about the lack of dataflow, CSP, etc. support in languages and their libraries for 30+ years. Fortunately, over the last 10 years, we have been getting programming language and libraries doing actors, dataflow, and CSP (or rough equivalent) properly, and most importantly – getting traction amongst programmers.
