Detailed Description

An assignment (=).

Assignment has a specific target (the left-hand side), and the value (the right-hand-side). The target may be multiple things, such as a variable VarExpr or field FieldAccessExpr. Note that some things such as indexed assignment []= become a CallExpr instead.
