A good syntax example:

a = sum (a, c)
a = mul (a, c)
a = div (a, c)

Another good syntax, I'm not a fan of, but at least intuitive and
learnt in school:

a = a + c
a = a * c
a = a / c

Bad syntax, not readable:

a += c
a -= c
a *= c

And your proposal: slightly different looking, but as bad
as above, at least I don't see any improvement of the look, actually
it makes even harder to see the beginning of the right part of assignment,
so IMO it is merely worsening of already bad syntax.
As for me, I would even prohibit all these +=  for the sake of readability.
