--- Comment #5 from Iain Buclaw <[email protected]> --- Initial steps to get the ball rolling on this: 1. Remove all complex and imaginary unit-tests from druntime and phobos. 2. Remove/Replace the druntime compiler-library helpers. - cdouble *_memset128(cdouble *p, cdouble value, size_t count) - creal *_memset160(creal *p, creal value, size_t count) 3. Remove built-in RTTI support in the compiler and run-time library. 4. Add deprecations for internal complex/imaginary helpers (core.internal.convert, core.internal.array.comparison, etc...) 5. Remove all support that was deprecated in (4). 6. Turn on -transition=complex in the compiler by default, so the deprecation warning is the default, deprecate the command-line switch. 7. Add -preview=complex (https://github.com/dlang/dmd/pull/12069). Though this could be done earlier. 8. Add new run-time support code for the "new" complex types for C ABI compatibility, this would have to be conditionally compiled in, likely using mixins to avoid triggering parser errors. 9. Make -preview=complex the default, deprecate the command-line switch. 10. Remove residual scaffolding around the deprecation phase of complex/imaginary numbers. ... or ... Jump straight to (6) and remove everything from druntime/phobos immediately. --
