Abstract
This paper proposes a minimal API that enables stackful context switching **without** the need for a scheduler. The API is suitable to act as building-block for high-level constructs such as stackful coroutines as well as cooperative multitasking (aka user-land/green threads that incorporate a **scheduling** facility).

Abstract
This is a proposal for a reduced initial set of features to support static reflection in C++. Specifically, we are mostly proposing a subset of features suggested in [[P1240R2]](https://wg21.link/p1240r2):

Abstract
Based on a few demonstrative applications, we claim that parameter reflection is an important feature that should be included in the initial specification for Reflection in C++26.

Abstract
Concurrent algorithms performing atomic RMW operations that discard the old fetched value are very common in high-performance computing, e.g., finite-element matrix assembly, data analytics (e.g. building histograms), etc.

Abstract
There are many contexts in which it is useful to perform the same operation on each subobject of an object in sequence. These include serialization or [formatting](https://www.boost.org/doc/libs/1_85_0/libs/describe/doc/html/describe.html#example_print_function) or [hashing](https://www.boost.org/doc/libs/1_85_0/libs/describe/doc/html/describe.html#example_hash_value).

Abstract
Postfix increment and decrement operators have a near-universal canonical definition. We propose that this default should be codified into the language by being able to `= default` such operators.
