You come across something syntactic that begins by opening a square

That's what's common here.
What goes*inside* those brackets can be one of two things:
1) A (possibly empty) comma-separated sequence of expressions
2) One or more nested 'for' loops, possibly guarded by 'if's, and a
single expression
So we have two subforms of the same basic syntax. The first one
corresponds better to the output format, in the same way that a string
literal might correspond to its repr under specific circumstances.
Neither is a literal. Neither is a call to a constructor function
(contrast "list()" or "list.__new__(list)", which do call a
constructor). So what is this shared syntax? Whatever word is used,
it's going to be a bit wrong. I'd be happy with either "constructor"
or "display", myself.
Construction. It includes an implicit constructor call and does more.
