Ralf W. Grosse-Kunstleve 129934ad9f Small cleanup/refactoring in support of PR #5213 (#5251) ... * Factor out detail/value_and_holder.h (from detail/type_caster_base.h) This is in support of PR #5213: * trampoline_self_life_support.h depends on value_and_holder.h * type_caster_base.h depends on trampoline_self_life_support.h * Fix a minor and inconsequential inconsistency in `copyable_holder_caster`: the correct `load_value()` return type is `void` (as defined in `type_caster_generic`) For easy future reference, this is the long-standing inconsistency: * dbf848aff7/include/pybind11/detail/type_caster_base.h (L634) * dbf848aff7/include/pybind11/cast.h (L797) Noticed in passing while working on PR #5213. * Add `DANGER ZONE` comment in detail/init.h, similar to a comment added on the smart_holder branch (all the way back in 2021).		2024-08-13 09:22:45 -04:00
