Show HN: clic - a CLI stack-based calculator in C#

Clic is a stack-based CLI calculator that stores its stack and variables across invocations and also supports a REPL (read/eval/print loop) mode for interactive use. It began as a sample program for my .NET CLI library, Cliffer, but I've now spun it out into its own repository.

* Basic mathematical operations and functions supported.

* Three built-in constants: e, pi, and tau (configurable constants are coming)

* Macro support for creating your own combinations of existing commands and macros.

* Runs on Linux, macOS, and Windows (and any other platform supported by .NET 8.0).

Thank you for taking the time to try clic. Please let me know what you think! Suggestions and criticisms are welcomed.
