I’m personally quite happy with the choice of strings, especially 
the token delimited strings, token strings, and so on. I do wish 
token strings were more conducive to concatenation because they 
usually still have syntax highlighting, making them work well 
with rudimentary mixins, but if you need to use `{` then you 
can’t easily cut them off to `}~insert~q{` other text. Thankfully 
IES partially solves this, but it’s maybe a little overkill for 
most of my use-cases (fast code generation), so I’ll just put up 
with having my code be all one colour.
