Can you please fill a ticket for this? The main problem is with 
compilers without variadic templates. Implementing piecewise construct 
for C++03 required a lot of job due to the internal C++11 pair 
emulation, so I decided to implement it later than some other neede 
features. I'll take a look to Unordered implementation to get some 
inspiration.

However I'm afraid I won't have time to implement it shortly. We can 
maybe start with compilers supporting variadic templates and support 
other compilers in a future release.

Best,
