For end users not familiar to D's new string interpolation 
solution. It could take a lot more time for them to figure out 
what just happened and to fix their code when something 
unexpected happened. This could be much more than the time to 
instantiate templates.

I know this try and error will happen, hopefully, only once to 
each user but every compile would take time to do the template 
stuff. But the time to make functions written in the future fo 
correctly handle the DIP's implementation is also needs to be 
considered.
