If local const#366
Conversation
The `if local` RFC (luau-lang/rfcs#238) allows a `local` or `const` binding in the condition of an `if`/`elseif` statement or expression, scoping the variable to the `then`-block: if local player = getPlayer() then print(player.Name) end Grammar: ('local' | 'const') Name [':' Type] '=' exp, parsed as the entire condition. `local` is a reserved keyword so `if local` is unambiguous; `const` uses one token of lookahead (`const` followed by a name is a binding, otherwise it stays a plain variable). - New `IfConditionBinding` node holding the local/const token, name, optional type specifier, and `=`. - Optional `binding` field on `If`, `ElseIf`, `IfExpression`, and `ElseIfExpression` (cfg-gated behind `luau` for the core structs). - Unsupported forms fail with clear errors: multi-return bindings and compound conditions.
