 /**
- * Definition of a variable as a statement inside a function. It requires a type name (which can
- * also be "var") but the actual assignment can be missing.
- * Examples: var a = 2; uint256 a;
- * As a second form, multiple variables can be declared, cannot have a type and must be assigned
- * right away. If the first or last component is unnamed, it can "consume" an arbitrary number
- * of components.
- * Examples: var (a, b) = f(); var (a,,,c) = g(); var (a,) = d();
+ * Definition of one or more variables as a statement inside a function.
+ * If multiple variables are declared, a value has to be assigned directly.
+ * If only a single variable is declared, the value can be missing.
+ * Examples:
+ * uint[] memory a; uint a = 2;
+ * (uint a, bytes32 b, ) = f(); (, uint a, , StructName storage x) = g();
