Vision/2016H2

Meta

This document discusses the high-level vision for D. It is revised every six months (January and July).

Note: This document focuses on goals the D leadership will personally enable or make happen. Other contributions that don't require their help are always welcome.

H2 2016 Priorities

• Improve or replace the GC with a more efficient one
• Eliminate Phobos dependency on GC (in other words, make GC opt out a viable and simple option).
• Flesh out and solidify std.experimental.allocator
• Improve compiler support so ref counting can be done @safely.
• Improve C++ inter-operability: struct mangling, Windows exceptions
• Fix problems with excessively long mangled names
• Improve internal memory management of compiler
• Continue improving DMD front end internals
• Low-hanging GC allocator optimization (thread cache, better data structures)
• Fast CTFE interpretation (rather simple mem leakage fix now, new architecture later)
• Usable/useful escape reference analysis (finished DIP25, scope methods to avoid escaping of this, in = const scope, D variadic arguments) to enable more efficient resource management (see example)
• More stable release model, better integration of fixes, maintaining LTS releases for professional users
• Better management of language and phobos development, consensus on strategies, basic project management for bigger features, better administration of DIPs and module review queue
