Concepts don't do that either. I do agree we could and should do a 
better job at testing templates against bare minimum structures that 
pass their constraints (e.g. test input range algorithms with true input 
range, which are indeed one-pass). Again, concepts won't help there 
either - it's not like we claim to support input ranges and then call 
.save against them. That's not a frequent bug.
