Establish a principle that understanding the meaning and performance should not depend on expensive context, and explain what makes context expensive.

Low context-sensitivity principle
Table of contents
Problem
Carbon needs a consistent policy on how willing we are to make syntax dependent on context.
Background
Rust has a statement of their ergonomic principles that talks about their approach to context dependence.
Proposal
We propose adding
(docs/project/principles/low_context_sensitivity.md)[/docs/project/principles/low_context_sensitivity.md],
which has the details.
Rationale based on Carbon's goals
This proposal supports the goal of making Carbon code easy to read, understand, and write particularly prioritizing "read and understand" over "write".
It supports software evolution by allowing code to be moved or refactored with fewer changes.
Further it supports developing performance-critical software in Carbon by making performance predictable.
