I thought the reason was that every instance of the template will need a
vtable entry, and the compiler may not be able to know beforehand which
instances will actually exist? You *could* in theory have the compiler
scan the entire program for all instances, I suppose, but that will
prevent incremental compilation and loading of dynamic libs, OSS or not.
Plus it may slow down the compiler significantly.
