Thanks, Matz - so cool to get a quick reply!  I guess it was the things 
like "sub", "gsub", "delete", etc. (all having both forms) that tripped 
me up, especially since "insert" seemed like an inverse of "delete". 
"concat", since it is like the "<<" operator (as well as "replace", like 
the "=" operator), didn't catch my eye in the same way.  Is "insert" 
fundamentally different than "delete" based on the two rules in the link 
provided in the previous post?  Ah, I'm probably splitting hairs, being 
a perfectionist...!
