+- In `!$DSL START STENCIL` and `!$DSL START FUSED STENCIL`:
+  - each argument (`name` included) should appear on a new line and aligned with the beginning of the first argument (generally `name`);
+  - any equal sign `=` should be preceeded and followed by a single space;
+  - the opening and closing round bracket should be followed and preceeded by a single space, respectively. Ignore this if the statement is on a single line.
+- In `!$DSL DECLARE`:
+  - each argument (`type` included) should appear on a new line and aligned with the beginning of the first argument;
+  - any equal sign `=` should be preceeded and followed by a single space;
+  - any comma `,` should be followed by a single space, but no space should be added before;
