I don't think having stl only containers with rvalues support is necessary. 
After all you want simplest version - you get it.

P.S. as for compilation time overhead, it's difficult to get any reliable 
quantative data. It depends on too many factors including the complexity of 
the code by itself, compiler, debug/release mode and how heavy FOREACH is 
used.
