## description this pr adds [match guards](https://doc.rust-lang.org/reference/expressions/match-expr.html#match-guards) to match patterns ```nushell match $x { _ if $x starts-with 'nu' => {}, $x => {} } ``` these work pretty much like rust's match guards, with few limitations: 1. multiple matches using the `|` are not (yet?) supported ```nushell match $num { 0 | _ if (is-odd $num) => {}, _ => {} } ``` 2. blocks cannot be used as guards, (yet?) ```nushell match $num { $x if { $x ** $x == inf } => {}, _ => {} } ``` ## checklist - [x] syntax - [x] syntax highlighting[^1] - [x] semantics - [x] tests - [x] clean up [^1]: defered for another pr |

Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
