To emphasize the equal.

Code:


if ( (a < 0 and a < 9) or (a == 0) ) {
  //this avoid the subtle <= that may be overlooked more easily than an extended condition. 
  //Code maintenance is more important than performance most of the time. Brain time is more precious than CPU time.
  ...code...
}

I can see that that would be less easy to skip over or mistype than "=".

I can imagine times when being able to copy the (0,9] syntax in a spec into the code would make it clearer that the code limits match the spec. On the other hand when implementing and debugging the code, the <= syntax or your separate < and = make it clearer what the code is doing (when (0,9] is used infrequently).
