good reason?? because someone is too lazy to type 4 more characters?
yes, i'm counting the readability spaces which could easily be left
out...

4 characters in your case, but if you have for example:
CALL_LVL [ LOCAL_CALL ] := CALL_LVL [ LOCAL_CALL ] + 1 ;
and you write instead:
CALL_LVL [ LOCAL_CALL ] += 1;
it's more than 4 chars, and it's easier, when it comes to changes,
and and and ...
This is only a simple example; consider arrays with more indexes and
record components and pointer references ...
BTW: the two statements are not equivalent, if the index expression
contains for example a function call with side effects :-)
PL/1 is another language which has been enhanced to support this
notation some years ago.
Kind regards
