Can you do that form of refactoring (specifically for a text
formatting function such as the implementation of printf posted
earlier) without sacrificing performance?

C++ basically sucks today if you use the output streams for
formatting instead of snprintf style format specifiers,
not to mention making maintenance (and L10N/I18N more complicated).

(note that the formatting example was used in a bare-metal
high-performance hypervisor on small supercomputer written
in C++.   No libraries, no STL, no exceptions, no RTTI,
just C with classes - because every cycle wasted in the
hypervisor is not available to user code).
