I bet it works very well actually.

variable1 = open(file)
variable2 = variable1.write(xxx)
variable3 = variable1.close()

GRC knows that variable2 and variable3 depend on variable1, but 
variable2 and variable3 are not dependent upon other, so their order 
does not matter.

In reality, this is a hack, and you are abusing what variables are and 
what they represent. What you would really want to see is:

variable1 = open(file)
variable1.write(xxx)
variable1.close()

So, take my advice from my previous email, and encapsulate this code in 
a custom grc block wrapper, and you will get exactly what you are 
looking for.
