Question:Maple 2015 vs Maple 2018: elements of table are not printed the same way

Hi everybody,

 

Written in Maple 2015
restart:
t := table([1=table([a=123]) ]):
save t, MyFile:
restart:
read MyFile:
t[1][a] := 321;

The answer is  t[1][a] =321 (here a double underscore)

Now I read MyFile from Maple 2018
restart:
read MyFile:
t[1][a] := 321;

The result is   (t[1])[a] = 321   (still a double undercsore but the first level is enclosed between parentheses).

For a more hierarchical table, all the entries but the deeper one are between parentheses.

Does this difference in representations mean something about the inner representation of a table ?

Thank you all
