+# Builtin Truthy & Falsy Type Aliases
+
+## Summary
+
+add built-in type aliases `truthy` and `falsy` and update analysis stringification for these representations
+
+## Motivation
+
+its very inconvenient to type `~(false?)` (truthy) / `false?` (falsy)
+
+currently this requires type functions but im going to larp negation syntax existing for the sake of this rfc
+
+## Design
+
+see [Summary](#Summary).
+
+## Drawbacks
+
+- no drawbacks
+
+## Alternatives
+
+- do nothing. this would make many people very sad, see [2516](https://github.com/luau-lang/luau/issues/2516)
