+   BYTES_TO_EXP_ELEM(length) elements containing the data of the
+   string, followed by the length again and the opcode again.
+
+   Note this is used by C++, but not C.  The C parser handles local

+   in C++ if the function/method name is not quoted, like e.g.:
+
+     p S:method()::var
+     p S:method() const::var
+
+   If the function/method is quoted like instead:
+
+     p 'S:method() const'::var
+
+   then the C-specific handling directly in the parser takes over (see
+   block/variable productions).
+
+   Also, if the whole function+var is quoted like this:
+
+     p 'S:method() const::var'
+
+   then the whole quoted expression is interpreted as a single symbol
