 ### Assignment
 
-An *assignment* is one of the four rules containing `ASGN`. It is evaluated by first evaluating the right-hand-side `subExpr`, `FuncExpr`, `_m1Expr`, or `_m2Exp_` expression, and then storing the result in the left-hand-side identifier or identifiers. The result of the assignment expression is the result of its right-hand side. Except for subjects, only a lone identifier is allowed on the left-hand side and storage is obvious. For subjects, *multiple assignment* with a list left-hand side is also allowed. Multiple assignment is performed recursively by assigning right-hand-side values to the left-hand-side targets, with single-identifier (`s`) assignment as the base case. When matching the right-hand side to a list left-hand side, the left hand side is treated as a list of `lhs` targets. The evaluated right-hand side must be a list (rank-1 array) of the same length, and is matched to these targets element-wise.

 *Modified assignment* is the subject assignment rule `lhs Derv "↩" subExpr`. In this case, `lhs` should be evaluated as if it were a `subExpr` (the syntax is a subset of `subExpr`), and the result of the function application `lhs Derv subExpr` should be assigned to `lhs`, and is also the result of the modified assignment expression.
