What should be added to C, call it PL/2

[Dean Elsner]

Sorry, I don't think you can call it PL/2!
IBM was going to call PL/1 "NPL" (New Programming Language?) until
National Physical Laboratories told them not to. They then registered
names PL/1 ... PL/100 (!). I don't think they reserved PL/0.
I don't know what 'registered' means here, but I presume trademarked.
This is from memory, and may be wrong.
