In StreamGroovyMethods, I created a size() method for Stream that is an alias for count():
https://github.com/apache/groovy/pull/2247 (Suggested on Slack by Vampire aka Björn Kautler) Let me know if you have any feedback. One of the pain points Groovy proposes to offer is always having a size() method on an aggregate thing and relieving the developer from having to know whether that thing offers size(), length, length(), count() and other options. So, I am +1 on adding this in Groovy 5. It appears to me to be like a missing feature we didn't spot for earlier Groovy versions, so I am thinking we should backport to GROOVY_4_0_X. Thoughts? Cheers, Paul.
