https://www.gnu.org/software/bash/manual/bashref.html#Shell-Parameter-Expansion,
particularly as quoted below:

address@hidden
   The expansion is either a transformation of the value of parameter
or information about parameter itself, depending on the value of
operator. Each operator is a single letter:
   [...]
   A
      The expansion is a string in the form of an assignment statement
or declare command that, if evaluated, will recreate parameter with
its attributes and value.
   [...]
   If parameter is address@hidden or ‘*’, the operation is applied to each
positional parameter in turn, and the expansion is the resultant list.
[...]
   The result of the expansion is subject to word splitting and
pathname expansion as described below.

HTH.
