Why you should name types?

I tried the upper most example and changed the name in the last For-loop to this:

For a.sprite= Each sprite 
	Print a\LOCY
Next 

I think Sintetik was asking: why should you give a name to the type, as it doesn't matter what name you give?

In my example, the variable "a" (or type instance) didn't exist or doesn't get declared.
But Blitz doesn't give me an error on it.

So you could create this program:

Type SPRITE 
	Field LOCX 
	Field LOCY 
	Field CURRENTFRAME 
	Field MAXFRAME 
End Type 

For temp = 1 To 5 
	cats.sprite = New sprite 
	cats\LOCX = Rand(100) 
	cats\LOCY = Rand(200) 
	cats\CURRENTFRAME= Rand(1,8)-1 
	cats\MAXFRAME= 8 
Next 

For a.sprite= Each sprite 
	Print a\LOCY
Next 

And it still does work.
In my opinion, there no need the give a type instance a name, like this:

cats.sprite = New sprite 

Why not just do:

New sprite

And use this routine to run through them:

For Each sprite 
	Print sprite.LOCY
Next 

This could make more sense (to me anyway).
