Summary of Changes

Hello @xushiwei, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request adds a new documentation file, 'doc/fncall.md', which comprehensively describes the unified function model within the XGo language. The document elucidates how commands, traditional function calls, and operators are all treated as function invocations, providing a consistent mental model for developers. It further categorizes and explains the usage of built-in functions, package functions, and object methods, highlighting XGo's specific syntactic flexibilities like optional parentheses and lowercase calling conventions for improved readability and Go compatibility.

Highlights

• Unified Function Model: Introduces the core concept that commands, function calls, and operators in XGo are all fundamentally function invocations, promoting consistency and intuition.
• Function Categories: Details the three main types of functions: built-in (e.g., 'echo', 'panic', operators), package-based (requiring imports), and object methods (e.g., string and time methods).
• XGo Specifics: Explains unique XGo conventions such as the optional parentheses for zero-parameter functions/commands and the ability to call uppercase-exported Go functions using lowercase names in XGo.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request introduces new documentation for commands and function calls in XGo. The document is well-written and clearly explains the unified function model. I have identified a couple of minor inconsistencies in the examples and summary, for which I've provided suggestions to improve clarity and correctness.
