>+        Since ES6, expressions like 0++, ++0, 0 = 0, and 0 += 0 are all specified as early errors:

>+            https://tc39.github.io/ecma262/#sec-assignment-operators-static-semantics-early-errors
>+
>+        We currently throw late ReferenceErrors for these; let's turn them into early SyntaxErrors.
>+        (This is based on the expectation that https://github.com/tc39/ecma262/pull/1527 will be accepted;
>+        if that doesn't come to pass, we can subsequently introduce early ReferenceError and revise these.)

>+        (JSC::PrefixNode::emitBytecode): Add an assert for "function call LHS" case.
>+
>+        * parser/ASTBuilder.h:
>+        (JSC::ASTBuilder::isLocation): Added.
>+        (JSC::ASTBuilder::isAssignmentLocation): Fix strange parameter name.
>+        (JSC::ASTBuilder::isFunctionCall): Added.
>+        (JSC::ASTBuilder::makeAssignNode): Add an assert for "function call LHS" case.

>+        (JSC::SyntaxChecker::isAssignmentLocation): Fix incorrect definition to align with ASTBuilder.

>+        * parser/Nodes.h:
>+        (JSC::ExpressionNode::isFunctionCall const): Added.
