This tests the fix for PR22010, where namelists were not being written to +! and read back from modules. It checks that namelists from modules that are +! selected by an ONLY declaration work correctly, even when the variables in +! the namelist are not host associated. Note that renaming a namelist by USE +! association is not allowed by the standard and this is trapped in module.c. +! +!
