IMPORTING jar-files with the NetRexx import statement

[Thomas.Schneider.Wien]

Wouldn't it be nice when we could enhance the NetRexx import statement
(directive) to be
able to directly refer to a jar file, ie.

import org.NetRexx.Rey.ReyR.jar   -- import all classes fo the jar

*and/or*

import org.NetRexx.Rey.ReR.jar/ReyRand.class  -- import the 'Random
functions' only
??

This would bypass the need to update the classpath for each jar-File you
are using,
and might be also used to DOWNLOAD this jar file on request from the URL
inducated.


What do you think ?

No!  This makes no sense; the language shouldn't be aware of JAR files, that's an implementation detail which should be hidden from the program.  The import statement is for importing classes and/or packages and it does this quite well.

You have now made your program dependent on specific naming conventions,
extension conventions, and file system conventions that Java (by
definition, almost) strives to avoid.
