I do not like <-

I like code that looks clean. Using <- all over the place,
makes the code looks little more ugly than using :=

I think ":=" and "="  is a better choice than "=" and "==" myself,
for readability purposes if nothing else.

That is why I do not like Fortran choice of a comment line, which is "!"

A very ugly symbol for a very common operation.

Ada's "--" is much more pleasing to look at, more smooth indicator of
a comment line and is not sore to the eye to look at it like ! is.

I have no idea who selected ! for comment in fortran, I think it was
bad choice, IMNSHO.
