I believe that
name,'=: ',5!:5 <name
should give a definition for any valid name which is suitable for use
in a script file.
The deficiencies I am aware of for 5!:5 have to do with using its
result as an argument for (".)
When I looked at your code to see what you were not using 5!:5 for, I
see that you are not using it for nouns. But I believe that all bugs
involving 5!:5's treatment of nouns have long since been fixed.
Am I missing something important?
Thanks,
