You can define commands (like functions) like this (in the shell if you want for easy trial and error):
# Returns indices that would sort the input list
def argsort [--reverse (-r)]: list<number> -> list<int> {
enumerate | sort-by item --reverse=$reverse | get index
}Then you get nice help like this "for free":
No, this is bad UX. The asymmetry violates the principle of least surprise.
What --all conventionally means:
A flag like --all should modify the scope or filtering of output, not the fundamental preconditions for the command to execute. Users expect flags to be additive or parametric modifications to a base behavior.
Examples of expected behavior:
| Command | Without flag | With --all / -a |
|---|---|---|
ls vs ls -a |

Cox’s theorem proves that probability theory is the unique consistent framework for reasoning under uncertainty.[1][2] Any system satisfying basic consistency requirements must be isomorphic to probability theory.
This framework is compositional over viewpoints: you assign probabilities over models/hypotheses and update via Bayes’ rule. Aumann’s Agreement Theorem shows that rational agents with common priors who update on shared evidence converge in their beliefs.

Methodology: Content generated through web research and synthesis in response to user prompts requesting (1) three parallel histories (generous, negative, neutral) of Python package management tools from 1998-2025, then (2) a rethreading of this history by problem domain rather than chronologically. User provided the conceptual framework (spreadsheet metaphor: problems as rows, tools as columns) and iterative feedback that shaped the structure and tone.

Three parallel histories of Python package management from 1998 to 2025, presented from different perspectives: a generous account focusing on people and progress, a subtly negative account emphasizing accumulated difficulties, and a neutral technical timeline.
Status of This Memo
This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements.
Abstract
This document describes the Unibro Protocol (UBP), a lightweight, zero-configuration protocol enabling seamless social interoperability between individuals who prioritize genuine human connection over status signaling. While other demographic groups have failed to achieve comparable social coordination (see Section 8: Related Work), the target user base has demonstrated organic ability to form supportive networks across diverse contexts. This specification formalizes observed behaviors to enable broader adoption.
The Nix ecosystem encompasses a variety of tools, features, and methodologies that have evolved over time. Understanding how these components relate can clarify their purpose and usage. They can generally be categorized as:
Here's a breakdown of key components:
