The Pascal 'with' statement is among the most hated features of
Pascal and was not copied in successor languages like Ada or Modula-2.
It was typically replaced by record constructors, such as

This is quite similar to lisp's let.
You can do almost anything with blocks/closures.
Although not relevant in most cases, there is a small performance price to pay
- but again this is

I’ve noticed that as we’ve progressed there has been a move to more concise and
fluid code - e.g. I quite like the new String streaming stuff
