Melody will automatically escape characters as needed. Quotes (of the same kind surrounding the literal) should be escaped\n\n### Raw\n\n- \u003Ccode>\\`...\\`\u003C\u002Fcode> - added directly to the output without any escaping\n\n### Groups\n\n- `capture` - used to open a `capture` or named `capture` block. capture patterns are later available in the list of matches (either positional or named). equivalent to regex `(...)`\n- `match` - used to open a `match` block, matches the contents without capturing. equivalent to regex `(?:...)`\n- `either` - used to open an `either` block, matches one of the statements within the block. equivalent to regex `(?:...|...)`\n\n### Assertions\n\n- `ahead` - used to open an `ahead` block. equivalent to regex `(?=...)`. use after an expression\n- `behind` - used to open an `behind` block. equivalent to regex `(?\u003C=...)`. use before an expression\n\nAssertions can be preceeded by `not` to create a negative assertion (equivalent to regex `(?!...)`, `(?\u003C!...)`)\n\n### Variables\n\n- `let .variable_name = { ... }` - defines a variable from a block of statements. can later be used with `.variable_name`. Variables must be declared before being used. Variable invocations cannot be quantified directly, use a group if you want to quantify a variable invocation\n\n  example:\n\n  ```rs\n  let .a_and_b = {\n    \"a\";\n    \"b\";\n  }\n\n  .a_and_b;\n  \"c\";\n\n  \u002F\u002F abc\n  ```\n\n### Extras\n\n- `\u002F* ... *\u002F`, `\u002F\u002F ...` - used to mark comments (note: `\u002F\u002F ...` comments must be on separate line)\n\n## File Extension\n\nThe Melody file extensions are `.mdy` and `.melody`\n\n## Crates\n\n- `melody_compiler` - The Melody compiler [📦](https:\u002F\u002Fcrates.io\u002Fcrates\u002Fmelody_compiler) [📖](https:\u002F\u002Fdocs.rs\u002Fmelody_compiler)\n- `melody_cli` - A CLI wrapping the Melody compiler [📦](https:\u002F\u002Fcrates.io\u002Fcrates\u002Fmelody_cli) [📖](https:\u002F\u002Fdocs.rs\u002Fcrate\u002Fmelody_cli)\n- `melody_wasm` - WASM bindings for the Melody compiler\n\n## Extensions\n\n- [VSCode](https:\u002F\u002Fmarketplace.visualstudio.com\u002Fitems?itemName=yoavlavi.melody)\n- [IntelliJ](https:\u002F\u002Fplugins.jetbrains.com\u002Fplugin\u002F18693-melody)\n\n## Packages\n\n- [NodeJS](https:\u002F\u002Fwww.npmjs.com\u002Fpackage\u002Fmelodyc)\n- [Deno](https:\u002F\u002Fdeno.land\u002Fx\u002Fmelody)\n\n## Integrations\n\n- [Babel Plugin](https:\u002F\u002Fwww.npmjs.com\u002Fpackage\u002Fbabel-plugin-melody)\n\n## Performance\n\nLast measured on v0.20.0\n\nMeasured on an 8 core 2021 MacBook Pro 14-inch, Apple M1 Pro using [criterion](https:\u002F\u002Fgithub.com\u002Fbheisler\u002Fcriterion.rs):\n\n- 8 lines:\n\n  ```\n  compiler\u002Fnormal (8 lines)\n                            time:   [4.3556 µs 4.3674 µs 4.3751 µs]\n  slope  [4.3556 µs 4.3751 µs] R^2            [0.9996144 0.9996931]\n  mean   [4.3377 µs 4.3678 µs] std. dev.
