+**Multi-line strings** use backtick delimiters (`` ` ``). They may span multiple lines and support the same escape sequences as regular strings (`\n`, `\t`, `\r`, `\\`, `\"`, `` \` ``, `\0`). Content between backticks is taken verbatim (no indentation stripping).

+shader_src := `#version 330 core
+void main() {
+    gl_Position = vec4(0.0);
+}
+`;
+```
+
+**Heredoc strings** use `#string DELIMITER` syntax (inspired by Jai). Content is completely raw — no escape processing. The delimiter is any identifier. Content starts after the newline following the delimiter and ends when the delimiter appears at column 0 of a line.
+```sx
+vert_src := #string GLSL
+#version 330 core
+void main() {
+    gl_Position = vec4(aPos, 1.0);
+}
+GLSL;
