I use `bc -l`.  I've been using it for so long now that I can't remember 
exactly what clued me into needing `-l`, though I have a vague 
recollection of a friend of mine telling me about it.  I agree that having 
anything other than `-l` as the default is rather nuts.  I've been typing 
`bc -l` for solong that to not type `-l` is an effort.
