+ What seems to be happening is that whatever is inside the [loop
+ interpolate=1][/loop] is processed only once (except for the [loop]-related
+ tags) and repeated as many times as needed.
+ 
+ This way, the following code:
+ 
+ ===================
+ 
+ [set my_stores_bought_from]store1 store2[/set]
+ [perl]
+ 	my( @stores ) = split " ", $Scratch->{my_stores_bought_from};
+ 	sub my_next_store { return shift @stores };
+ 	sub my_reset_stores { @stores = split " ", $Scratch->{my_stores_bought_from};
+ return; };
+ 	return join " ", "current stores:", @stores, "<br>";
+ [/perl]
+ [loop interpolate=1 prefix=store arg="[scratch my_stores_bought_from]"]
+ 	[store-code]: [perl]my_next_store();[/perl]<br>
+ [/loop]
+ [perl]my_reset_stores();[/perl]
+ [loop prefix=store arg="store1 store2"]
+ 	[store-code]: [perl]my_next_store();[/perl]<br>
+ [/loop]
+ 
+ ===================
+ 
+ will generate:
+ 
+ current stores: store1 store2
+ store1: store1
+ store2: store1
+ store1: store1
+ store2: store2
+ 
+ Notice that when "interpolate=1" is used, my_next_store() is called only once.
+ When it is not used, it is called twice.
