From 6ab9c3732793b6fd40e6388cf1b08756194c0ea6 Mon Sep 17 00:00:00 2001 From: Quinn Stephens Date: Thu, 7 Nov 2024 16:59:19 -0500 Subject: [compiler] Parse return statements Laid groundwork for statements and AST trees. Currently return values are not supported, expression parsing must be implemented first. Also stopped dumping parsed type definitions.
