The only reason to use main function is that the java command line tool requires the signature, along with some complicated -cp, -X, -XX, and -D arguments.
My thoughts:
- Aren’t people from Java world who know those complicated arguments of the
javacommand line tool also understand the convention ofmain? Which is more natural to them,def mainorprogram Main? - Are there other approaches to launch Scala applications for people who don’t use
javacommand line tool? Is an average Scala starter expected to understand thejavacommand line tool？
