JOIN and REJOIN will return the same datatype as the first item you
give them, so you can avoid doing a lot of TO-* stuff if you don't use
strings for everything (and look at the source for them so you can see
what they do under the hood). INSERT, CHANGE, and APPEND are often all
you need, but one of the most important things is to look at how
things read (i.e. is the intent clear) based on the words you're
using.
COMPOSE is another handy tool, as is standard block notation;
sometimes you don't really need things joined if the code processing
them can operate on a block. i.e. don't REJOIN things in one place
only to split them back apart somewhere else if you can avoid it.
Path notation is also handy, but it looks like you know about that.
