Beyond D2

Motivation

This page came up from email thread [1]; the goal is to have a central place to discuss potential flaws in D2's design or features that are too late to integrate in D2 but could be useful for a potential successor.

D questionable design choices

• is virtual by default a good idea with separate compilation model?
• can we get rid of @property?
• improved dmd/rdmd command line: [DIP41: dmd/rdmd command line overhaul]
• can we get rid of C-style expression lists in parenthesis; these would be used for tuples

Feature Wish List for hypothetical D3

• python style named parameter arguments
• AST macros
