OSSP val - Value Access
TODO
o dynamic variables: function pointer for set/get
o in combination with var lookups, each variable should have
dump/print/output feature/function which results the value (integer,
string, struct, etc.) always as a string (stringify function)
o access control feature: val_reg(<acl>, ...)
val_get(<access-level>, ...)
for use in combination with var in order to allow all internals to
be stored and registered in val structure but allow variable lookups
only to access public/whatever type variables.
