No need; the module name that you will get back from Smalltalk  
listLoadedModules can include version info. See implementors of  
#moduleNameAndVersion and in particular the LargeIntegersPlugin  
version. Of course, you will pay the cost of getting all the info for  
all loaded plugins when using this. In some cases it may be important  
to find a plugin version quickly and then an extra prim in the plugin  
is possibly useful. However I don't think I would suggest following  
the bizarre usage of LargeIntegersPlugin>primGetModuleName and  
primCheckIfCModuleExists
