*Hello all,*

My name is *Kamalesh Lakkampally,* founder of an EDA startup, I am
submitting the attached draft proposal (*PnnnnR0*) for consideration by the
Evolution Working Group (EWG).
This proposal introduces a provisional *core-language extension*
enabling *fetch-only
instructions*—instructions that operate entirely in the processor’s fetch
stage and use a dedicated path outside the normal execution pipeline.

The goal is to support workloads where the execution order of micro-tasks
changes dynamically and unpredictably every cycle, such as *event-driven
HDL/SystemVerilog simulation*.
In such environments, conventional C++ mechanisms (threads, coroutines,
futures, indirect calls, executors) incur significant pipeline redirection
penalties. Fetch-only instructions aim to address this problem in a
structured, language-visible way.

I would greatly appreciate *feedback, criticism, and suggestions* from the
community.
I am also *open to collaboration.*

This is an early-stage concept, and I welcome any guidance on improving the
design, refining the semantics, or adapting the idea to better align with
the C++ abstract machine and WG21 process.

Thank you for your time, and I look forward to your comments.
