possible arguments are:
* promote - promote the argument from a variable into a constant
- * string_promote - same, but promote string by *value*
+ * promote_string - same, but promote string by *value*
* access_directly - directly access a virtualizable, as a structure
and don't treat it as a virtualizable
* fresh_virtualizable - means that virtualizable was just allocated.
