I assume your intention was to test class expression here. But this is parsing a
statement so you need add parens around the expression.

No, the "1," in front causes it to be parsed as a member-expression inside a
comma expression inside an expression statement.

But I put it in parens for more clarity.

Ooops

The 1 was lost in the noise.

+CheckError("1, class extends Array {};");
+CheckError("1, class C {};");
+CheckError("1, class C exends Array {};");
 
 CheckOk("let = 1;");
 CheckOk("{ let = 1; }");
