/*
 * Tests for the parser symbol psym_decl, which represents a declaration.
 *
 * Since C99, declarations and statements can be mixed in blocks.
 *
 * In C, a label can be followed by a statement but not by a declaration.
 *
 * Indent distinguishes global and local declarations.
 *
 * Declarations can be for functions or for variables.

// aligned, while local variables aren't.
