Updating a Map inside a For Loop?

Hi,

I wanted to know if it is bad practice to update a map inside a for loop.  When I say update I do not mean a DML update--as I know better! :)  I mean can I do a get on a map and a put on that same map inside a loop.  I want to read thorugh records in my loop and if I find a matching key in my map over and over, I want to keep updating the map with the latest records data?  Once out of the loop then I figure I should be able to do my DML on the map.
