Yes, it's a big deal. Any place that it's part of an API, it's a big deal. It 
forces you to create what are essentially useless variables all over the place 
if you require ref. We _will_ have a solution similar to const& at some point, 
and that's what the correct way to go to solve this problem will be, but that 
situation still needs to be sorted out (and the situation with DIP 25 - 
http://wiki.dlang.org/DIP25 - could have an impact on that given that it's 
also has to do with changes to ref).
