Templates are now in the namespace basic:: i.e `basic::value<>` Typedefs are in ircd::js:: matching the original non-template types. Ex. stack-duration type in template form is: `basic::value<lifetime::stack>` Ex. stack-duration type in typedef form is `value` Ex. heap-duration type in template form is: `basic::value<lifetime::heap>` Ex. heap-duration type in typedef form is: `heap_value`
