[Oorexx-devel] Question: an already required package will not get created from scratch, if in a different interpreter instance

[Rony G. F. <Ron...@wu...>]

Not sure whether this is a bug or working as designed (if so, perhaps it should get documented).

When using the "::requires" directive, a resolved package will get re-used (only at the very first
"::requires" will a call without arguments be carried out by the interpreter).

In an environment where multiple Rexx interpreter instances are employed, I would have expected,
that required Rexx packages get re-created from scratch upon when they are required the first time
in a new interpreter instance (e.g. so class or routine objects are distinct per Rexx intepreter
instance). In essence expecting that this gets "scoped" per interpreter instance like ".local"
(which gets created for each interpreter instance).

Further analysis shows, that the prolog code of required packages gets run on each new interpreter
instance, without re-creating the package separately for each interpreter instance. This may
indicate that this behavior is intended. If so, it should get documented with the ::requires
directive (or with the native RexxCreateInterpreter()-API).
