+ p S:method() const::var
+
+ If the function/method is quoted like instead:
+
+ p 'S:method() const'::var

+ "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
+ name and we don't use OP_FUNC_STATIC_VAR either. In that case, the
